Xorg log showing start, suspend and resume

After resuming from suspend to ram I experience corruptions on the whole
screen. I'm using a compositing desktop with gnome-shell but the corruption is
also visible in the text consoles. I can recover from the corruption and
continue work normally if I change the resolution or screen orientation.
This bug is present in the kernel versions 3.0 - 3.2rc2 and I think also in
some releases before them. The graphics card is a HD3870, X.Org X Server
1.11.1.902
The radeon module is loaded with dynclks=1 audio=1

Attached are pictures of the corruption and a my Xorg.log. Any other
information I can provide?
