Which is just fine by us, what Free Software would enforce the reduced quality output, macrovision, etc flags even if the driver exposed the functionality?
Granted there ARE some potential users who would want that, settop box makers who would be legally obligated, but there is always the closed driver for them to go along with other closed binaries such a product will involve.

Nope, I RTFA. AMD/ATI only released 2D info today, but are have promised the 3D stuff will follow. That means DRM (Direct Rendering Manager) stuff will be included. DRM (Data Restriction Managment/Digital Rights "Management") was not mentioned and probably won't be disclosed for the reasons I mentioned above. Plus if they disclosed the details it would make it trivial for Windows hax0rs to use that info to disable the nasty bits which would really annoy powerful interests. Not that they won't do it anyway via reverse engineering....

So what's changed?
I suppose it is the same as if Microsoft says Linux violated 235 patents [=vapor]. Or perhaps it is because someone wants to win the extra 178 customers from http://www.pledgebank.com/open3d :-) You know, there is this concept of first strike (not always nuclear-related like WP seems suggesting, can also work for kung fu or anything else).

I'm slightly worried that a skim through the PDFs reveals whole pages with no commentary at all (ie just lists of opaque register names with the comment field left blank). It may be that to video driver developers these registers are either superfluous or their purpose is so obvious that commentary would be redundant but I'd guess it'll be a few days until we know ?
Can anyone say whether the extent of the micro-management in this hardware is usual? e.g. you can control what RGB colour is used for the "black" sent when there is no colour signal, but not just with one register, there's a separate register for overscan, and for blanking, and its duplicated for each CRTC. That's just one example of the sort of thing I'd not expected to find on consumer hardware.
