Aaaaah, this machine doesn't have an APIC table so acpimadt doesn't
attach and cpu0's cpu_acpi_proc_id is thus the default 0 when acpicpu0,
which has proc_id == 1, tried to attach.
It looks like we need to make sure cpus are attached before acpicpu is
attached. I'm not sure how to do that, so in the mean time, Johan, can
you try applying the diff below and rebuilding the kernel and see if it
boots? This is just a revert of acpicpu.c rev 1.75 back to the old unit#
based matching.
