The same here as in comment #115: kernel 2.6.34-52 (2.6.34-52.1) from
Brian Rogers' ppa freezes the system.

Dell Optiplex GX60
00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01)

libdrm				2.4.20~glasen~ppa4
xserver-xorg-video-intel	2:2.11.0+git20100529~glasen~ppa2
mesa				7.7.1-1ubuntu4~gpufix1

The freeze happens at the first modeswitch, i.e. so early during startup
that I cannot dump an i915_error_state. My favourite kernel on this
system is a drm-intel-next one from the Ubuntu Kernel Team
2.6.34-997.201004191525, i.e. without the V9 patch. The later drm-intel-
next kernels from http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-
intel-next also freeze the system at the first mode switch. The
201004191525 kernel shows an i915 error at about the same time when its
successors freeze but it continues:
