dmesg with 2.6.36-rc7

I'm experiencing a hard lock (i.e., no magic SysRq) after playing 
Penumbra Overture for about a minute on my ThinkPad t43p with kernel 
2.6.35 / 2.6.36-rc3. I'm using KMS. 2.6.34 works fine. I didn't test 
thoroughly with 2.6.35. With 2.6.36-rc3, I did not mess with any of the 
new power savings settings. I'm not using any xorg.conf, I'm using KMS. Without
KMS the problem does not occur. 2.6.34 is the last kernel that worked with KMS.

Some more info:
lspci says: ATI Technologies Inc M24GL [Mobility FireGL V3200] (rev 80)
System info: Slackware 13.1, Mesa 7.8.1, Xserver 1.7.7.

I did try other versions of mesa (including Gallium3D), but that did not make a
difference. Furthermore, I tried to bisect this problem, but ended up within
the range of 2.6.34-rc's, so I don't think that provided any help in this case.

I also wrote to dri-devel about this problem, but received no reply. I then
went to the radeon IRC-channel, where I was told that these complete hangs are
very hard to debug, but that it would help to have a Bugzilla report. I wasn't
sure whether or not to report this as a regression, so I chose not to. Please
correct me if I'm wrong!

I've attached some info that I hope might help, i.e. dmesg, Xorg.log and kernel
config for both kernel 2.6.34.7 (working) and 2.6.36-rc7 (not working).

In closing--I'd really like this problem to be solved, and I'd very much 
like to help out as much as I can.

Regards,

PJ
