Sigh. If you implement your drivers in userspace, you can simultaneously
tell your users to forget about suspending to disk, and possibly to ram.

Not true at all, you have to have a tiny kernel piece for this framework
to work properly, and just add the proper PCI suspend / resume portions
of the pci framework and it should work just fine.

Hi Nigel (*), could you expand on this? Would it really be impossible to do power management and such things if (most of) the driver code is moved to user space and why?
