suspend-to-disk doesn't work with DRI on albook with ATI Radeon 9600

[Gaudenz Steinlin <gaudenz@debian.org>]

Hi

Since upgrading to Xorg 7.0 I have 3D accelerated graphics working with
DRI and the r300 driver. But this breaks suspend-to-disk. The computer
resumes, but X does not restart. I have to kill the X server and restart
it manually. 

If I disable DRI (by not loading the X module) suspend-to-disk works
just as with xorg 6.8 (where AFAIK the r300 driver did not work and DRI
was disabled by default).

Suspend-to-RAM works even with DRI enabled.

Is there a way to make X handle suspend-to-disk even if DRI is enabled
or is this just not (yet) supported? Anything I could do to further
debug the problem?
