Sorry for my late response; this thread was lost in the mists of my mail

I would assume it does, but I don't currently have access to the machine
to tell for sure.  I saved a few things from the system: $DEBUGFS/dri/,
/var/log/syslog, /var/log/kern.log, and /var/log/Xorg.0.log.
Unfortunately I don't see any clues in these; if I've missed something
in these files that may help, let me know.  I also tried searching
through drivers/gpu/drm/i915/ of the Linux source, but my untrained eye
found no hints.

Next time I have access to the machine, I can check for KMS.  And if I
have time and it might help, I can build a new Linux image with
additional debugging options (let me know which, if any) enabled in the
configuration.

Thanks,
P. J.
