With the aforementioned kernel version, after a resume the screen stays black. Everything seems responding (wifi led blinking, reboot, ...).
After reading the logs between this kernel and 2.6.35-rc1-00194-gaef4b9a (known good), i think the problem is with this patch
drm/radeon/kms: make sure display hw is disabled when suspending
After I did apply the attached patch, the resume seems OK.
Don't know if it's the good solution...

Is this ok like this, I'm new at this thing (I'm just a poor tester/reporter ;-)
Thanks. I've sent the patch to Dave.
