radeon fails to start at all, even with a minimal xorg.conf. I simply
get booted into a 800x600 failsafe screen with my xorg.conf trashed.
That's 2.5 days wasted. For now I've gone back to proprietary and living
with no suspend/resume, but boy am I fed up with the whole thing.
Thanks for your help.
