Are you running GENERIC_LAPTOP?  At some point, someone included acpi 
in that kernel, which causes problems for my T42.  On -current, I have 
a custom kernel that includes

	no acpi0                at mainbus0

but I don't remember if 'no' is supported on 3.0.  My daughter is also 
running a custom kernel.  Anyway, I get that message if I boot the ACPI 
version; the fix is to build a kernel that doesn't have it.
