Dan,
something of an oblique answer I'm afraid but it might point you in the
direction of some useful resources.
I've recently been setting up my work HP nx9105 as a dual boot WinXP /
Ubuntu system. My main problem was USB not working. This turned out to
be ACPI related because of a BIOS bug. (Fix was to turn off ACPI and all
my USB devices snapped into use :o) )
My point is that the Ubuntu Wiki and forums have a lot of discussion
related to laptops and all things ACPI which may provide some ideas
about ways you can figure out a solution.
Regards,
Keith
