AMD has been rocking. The turn around they did on ATI has been fantastic, despite people bitching constantly it. (punishing people for trying to be your friends is not a useful path forward)
I wouldn't worry about Intel too much. They are a huge company and they are all just made up of groups of mostly autonomous organizations. So what one part of Intel does may have little or no bearing on what other parts of Intel. Ultimately I would rather have a Linux-free hardware a repeat of what happened with Intel GMA500's Linux support. Sometimes it's better to have no support then something like that.

Not so sure about that. If they have an agreement with Microsoft to keep some details of power management on new Atom processors secret, that might persist into newer versions, and ultimately hurt Linux on more and more of the low-end x86 processor space. Since they are taking on Android and iOS, I'm sure that this is Microsoft's desire; I'm not sure it's really in Intel's interest though.

I am pretty sure about that. From what I can tell this chip will sport a PowerVR-based IGP that is a descendant of the IPGs used in those old netbooks.
So it's extremely likely that; The 'secret' powermanagement has more then likely involve the video stuff, it's not Intel's 'IP' and they are not at liberty to make it public knowledge, and even if Intel wanted to run Linux on it it wouldn't work out any better then with the GMA500.

A widely missed comment in the press about the time the poulsbro (GMA500) scandal was winding down was Intel announcing that a whole line of Future atoms would use SGX technology (the producer of the poulsbro GPU).
My personal expectation is that Intel will be going back to the bad old days with the Atom line. I don't really expect the atoms to do well without Linux support so they will be shooting themselves in the foot.

Cedar Trail (latest-gen netbook) uses a SGX GPU core.

Right, but the next generation will stop using SGX graphics. Then everything will be fine.

Here you are served...
Microsoft's money rocks more than AMD.

building a chip exclusively for a hardware manufacturer is plausable (even if it's a bad idea, but if someone writes a big enough check, ok)
However, a chip that is going to be sold to many manufacturers that is locked to one OS seems 'odd'
but then again, nothing (except possibly stupid contracts with Microsoft) forces anyone to build any products around these chips. Yes they will be the latest and greatest, but are they really going to be enough better that they will be willing to lock themselves in like that?
Who wants a MS-only Atom? Posted Sep 15, 2012 7:21 UTC (Sat) by rvfh (subscriber, #31018) [Link]
I would expect Nokia to use this chip. The funny thing is that Intel hired quite a few people who got laid out by Texas Instruments after they got rid of the modem business, and that had been working almost exclusively with Nokia for a long time. History repeating itself?

My 1.5 year old AMD GPU still does not have any power management, meaning I have to statically set it to the lowest frequency if I do not want to burn up my computer. I do not think AMD's support is that good.

Fix your computer. It is not cooling correctly.

If you would like to stop being ignorant you can read this bug report: https://bugzilla.redhat.com/show_bug.cgi?id=702953
Still applicable even though very old.

If you take thermal "gun" to a laptop you'll find that the largest offenders for heat are the CPU and GPU, not necessarily in that order. CPU heat can be mitigated by a functional ACPI bytecode, GPU by the proprietary drivers. The issue with GPUs is a good portion of the features that make them fast, also makes them energy efficient, so they can't disclose one without compromising the other, classic catch 22.
It's also going to get worse before it gets better thanks to the rate of disposable platforms (SoCs), it's more efficient to get to market with a proprietary GPU driver, working closely with the GPU vendor, than it is fumbling through the opensource "equivalent" without any assistance from the vendor.
The only real way out of this is to establish an open GPU platform with a LGPL'ish license that's so good with power and performance that the status quo can't ignore the price differential.

In current release, I doubt that it is still applicable. Last openSUSE I installed X defaulted to 'mid' rather than performance, which very likely reduces power dissipation sufficiently. No reason to doubt Fedora 17 hasn't picked up the same upstream setting change.
Intel declares Clover Trail Atom processor a "no Linux" zone (ars technica) Posted Sep 15, 2012 21:38 UTC (Sat) by BrucePerens (guest, #2510) [Link] Huh?For most of these systems, the best power management is to run them full-out when they have work to do, and to keep the CPU halted when it's idle. The Linux kernel does that without either APM or ACPI. Just what kind of hardware do you have?
Intel declares Clover Trail Atom processor a "no Linux" zone (ars technica) Posted Sep 15, 2012 23:58 UTC (Sat) by mjg59 (subscriber, #23239) [Link]
Neither APM nor ACPI provide any kind of standardised power management interface for GPUs.
Intel declares Clover Trail Atom processor a "no Linux" zone (ars technica) Posted Sep 16, 2012 19:49 UTC (Sun) by BrucePerens (guest, #2510) [Link] It's the GPU driver's responsibility, right. A little surprising if AMD hasn't documented what to do.
Intel declares Clover Trail Atom processor a "no Linux" zone (ars technica) Posted Sep 16, 2012 21:08 UTC (Sun) by tuna (guest, #44480) [Link]
Why is that surprising. There are loads of stuff that AMD does not document regarding their drivers.

Surely you mean, you're setting it to low via variable in a small startup script. I used this with HD 4650 to reduce noise with FOSS driver, as it defaulted to performance rather than medium. In Console mode low was fine.
If you need working dynamic power management, there's the AMD Catalyst driver there's an article on Phoronix explaining the jam on dynamic powermanagement, which summarises hacker-AMD thread on such. This sort of whingeing, is just punishing a company that's trying to do the right thing, a rival forces Reverse Engineering.

Actually, I haven't been too enamored with ATI/AMD lately:
