Hi Perry.  The crash happens on gentoo-linux, both 32-bit and 64-bit hosts, using
the latest kernel from Linus.git.[1]

Hi Knut,
Yes I can transcribe the kernel oops console output (when I'm more awake) but
there are very few debugging symbols in the output.  Tomorrow I will try to
figure out where I need to compile in more debugging symbols

[1]  The latest OSE.svn will no longer compile against kernel 2.6.35 because of
recent changes to the kernel data structures in include/linux/drm/drm_crtc.h
