Michel,

xf86-video-ati git from today fails.  Applying the revert patch in the above message
fixes the problem.  Its an interesting bug in that the kernel change triggers the 
driver bug.  Might be a good idea to get this fixed, one way or another, before
-35 gets released?

Let me know if you want me to test anything.

Thanks,
Ed Tomlinson
