I could sort of almost repro this bug on my G45:

Steps:
1. install mesa 7.6.0~git20090928.6829ef74-0ubuntu1~xup~1 from X-Updates PPA
2. launch blender
3. press the "render this window" button (it's the upper right most button in the lower half of the screen, look for the tooltip)
4. _blender_ crashes and my intel driver spews nasty errors into dmesg, but Xorg remains running and usable

Using the current karmic mesa (7.6.0~git20090817.7c422387-0ubuntu6) nothing out of the ordinary happens.
I put all my dumps etc into bug 39488 which I marked as a duplicate of this one.

I even recorded a "dri_debug.tgz" even though what I saw was most certainly not a GPU freeze (unless they already merged that automatic GPU reset code which I don't think they did right?)
