That's very interesting - but if I understand correctly, you're booting
that E6400 with ACPI enabled in the kernel.  When I try that, it crashes
very early in the boot process, dropping into KDB.  Could it have one or
more corrupt ACPI data structures in the BIOS -- and is there any way to
fix this, if so?
