Hi Greg, hi stable kernel team,

Please consider the attached patch from Jérôme Glisse. It fixes drm radeon 
KMS after coming out from a snapshot cycle [1] - no matter whether I use 
userspace software suspend or TuxOnIce.

Verified on my notebook ThinkPad T42 and by cedric, the reporter of above 
bug.

Thanks.
