I think my comments were deleted when I made the attachments.  Oops.  Short
version: My glibc is compiled against 3.8 headers, so I resorted to a Fedora 18
disc to get 3.6.10 kernel results.  The resulting dmesg looks very accurate to
me, including the host bridge window errors and shared interrupts, so the dmesg
is attached.

For the 3.8 setup, I got the idea of booting to the video=1024x768M-8 at 75 screen
that I wanted to have.  I took the dmesg by booting to a blank screen, starting
X, and using an xterm to dump the message buffer.  There's a stack trace in
there that looks interesting.  fbset states that /dev/fb0 does not exist.

I'll try to get intel_gpu_tools working from 3.6 somehow.  [They're already
installed on my 3.8 system.]  That will be later, though.  I must get some
sleep.  Thanks for the quick reply!
