After some unknown period of time or activity, I get a GPU hang on my laptop (Lenovo R61, Core2Duo, Intel GM965 video). It seems to correlate closely with display power management kicking in, but I don't know if that is a coincidence. I will attach the dmesg output and intel_gpu_dump output, and Xorg.0.log taken after connecting to the system by SSH during the hang. This particular instance had the internal display (LVDS) and an extra display (VGA) active, but I have had what appears to be the same crash when only using the internal display. This is on Ubuntu 9.04 with updates from xorg-edgers and the latest available kernel package. uname -a: Linux fry 2.6.30-020630-generic #020630 SMP Wed Jun 10 09:04:38 UTC 2009 x86_64 GNU/Linux Xorg, Intel driver, etc. package versions: intel-gpu-tools: 1.0.1-0ubuntu0sarvatt2~jaunty libdrm-intel1: 2.4.11+git20090519.f355ad89-0ubuntu0sarvatt~jaunty xserver-xorg-video-intel: 2:2.7.99.901+git20090610.9d3c3b05-0ubuntu0sarvatt~jaunty xserver-xorg-core: 2:1.6.1.901+git20090523+server-1.6-branch.5cd5a012-0ubuntu0sarvatt2 libdrm-intel1 and libdrm2: 2.4.11+git20090519.f355ad89-0ubuntu0sarvatt~jaunty libgl1-mesa-dri and other mesa packages: 7.5.0~git20090609+mesa-7-5-branch.91923474-0ubuntu0sarvatt

For what it's worth, I have not seen this crash/hang on Fedora 11, using the latest updates from that distribution: uname -a: Linux fry 2.6.29.4-167.fc11.x86_64 #1 SMP Wed May 27 17:27:08 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux xorg-x11-drv-intel-2.7.0-7.fc11.x86_64 xorg-x11-server-Xorg-1.6.1.901-1.fc11.x86_64 mesa-libGL-7.5-0.14.fc11.x86_64 libdrm-2.4.6-7.fc11.x86_64
Unfortunately, I spoke too soon regarding the stability of F11's version of the Intel driver. While it did seem to last longer unattended, I just had a freeze on my Fedora 11 install as well. Same hardware. I will attached the GPU dump and dmesg output.

I think the Fedora 11 problem may be a different bug. Under my Ubuntu setup I only get hangs after DPMS kicks in. Fedora will hang during normal use.
I disabled display power management from the Gnome power applet, left my laptop alone for ~40 minutes under my Ubuntu install and came back to a live, functioning system. So my GPU hangs may be related to power management of some sort. I hope this helps to narrow down the potential issues.
