Hi,
It looks like there is an important bugfix in the 2.6.35 kernel for
issues involving intel GPUs, in particular the i945. Since the upgrade,
I have not had these issues anymore, however, I also have not been using
that computer a lot.
Anyway, here's the relevant change from 2.6.35-rc6:

commit 944001201ca0196bcdb088129e5866a9f379d08c
Author: Dave Airlie <airl...@redhat.com>
Date: Tue Jul 20 13:15:31 2010 +1000
drm/i915: enable low power render writes on GEN3 hardware.
A lot of 945GMs have had stability issues for a long time, this
manifested as X hangs, blitter engine hangs, and lots of crashes.
one such report is at:
https://bugs.freedesktop.org/show_bug.cgi?id=20560
along with numerous distro bugzillas.
This only took a week of digging and hair ripping to figure out.
Tracked down and tested on a 945GM Lenovo T60,
previously running
x11perf -copypixwin500
or
x11perf -copywinpix500
repeatedly would cause the GPU to wedge within 4 or 5 tries, with
random busy bits set.
After this patch no hangs were observed.

We should make sure to get this fix into the squeeze kernel!
