The debug.acpi.disabled setting allows me to load up the driver and
displays a usable X screen on the internal monitor - however, my
xorg.conf was configured to use the *external* monitor. When X quits
on the internal monitor, the console display reverts back to the
external monitor with a "scratchy" display.

I've also just updated the BIOS in the hope that it would resolve the
conflict, but that didn't appear to do anything.

I've also noticed that cbb0 complains about "Bad Vcc requested" on
boot and shutdown.

Thanks for looking into this, btw.
