I'm running 2.6.30.1 in my case.

And reverting the commit causes quite a bit of mayhem on my end. I got screen
corruption (still was able to interact with xterm, though) as well as this in
dmesg:

Also tried glxgears (probably a bad idea, but...

[ 6172.394899] [drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB !
--- repeated several times per second until X was terminated ---

I'm running the latest git versions of libdrm, mesa, and xf86-video-ati.
