Made no difference, today's git snapshot, 2.6.35-rc5-git4 w/ airlied + anholt 
drm git trees still hangs attempting to suspend. in Fedora, it drops to the 
Fedora logo w/ KMS mode then fails to finish suspending (moon light flashes 
off and on), I do hear the disk heads parking though.

I will look at bisecting this week when time permits. If anyone else might 
know what might be the issue it would save some time in the bisecting.


Thanks,
Shawn.
