i have an rs690 (onboard desktop mobo), 2.6.36-r5, xorg 1.9.2, mesa 7.9, and
xf86-video-ati 6.13.2.  i'm having similar issues when getting out of sleep. 
the display appears to be hung, and i have to switch to a console and back. 
usually, i have to wait awhile and the screen comes back.  i'll have to try
turning off my monitor off/on forcefully to see if that helps my monitor come
back.  sometimes it takes a minute if i just let it go.

i also suffer from the display randomly blanking for 1-3 seconds when the box
is busy.  it always comes back fine though... nonetheless really annoying. 
it's really bad if i don't set drm_kms_helper.poll = 0.  i'm thinking there's
something screwy going on with polling getting out of sleep.
