[Problem]
Screen corruption shown on resume when using KMS from the radeon-rewrite branch

[Versions]
libdrm - 2.4.12+git20090806.d74c67fb-0ubuntu1
linux - 2.6.31-6.25~radeon2
mesa - 7.6.0~git20090805.ac3de85e-0ubuntu1
xserver-xorg-video-ati - 1:6.12.99+git20090805.bd03977e-0ubuntu2

[Original Description]
When using the new ATI stack from the X-swat PPA (radeon-rewrite with DRI2 and KMS), suspend is broken on my Thinkpad T60 with ATI Mobile X1400. After waking up the system shows colorful vertical bars on screen. I'll attach a screenshot of that as soon as I can.

Also, dmesg is full of the following messages:

[ 9315.666488] [drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(7).
[ 9315.666491] [drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB !
