IMO, the quick solution also requires that MAX_APICID in
[amd64/amd64 | i386/i386]/local_apic.c needs to be changed
because lapic_create() checks if the passed apic_id > MAX_APICID.
Also in [amd64/amd64 | i386/i386]/mp_machdep.c checks in cpu_add()
if the passed apic_id >= MAXCPU. There are a couple other checks
in mp_machdep.c before converting to use the cpu_apic_ids array.
I was curious, and wrote up a patch file with the potential minor changes
for -current at http://www.casselton.com/~tinguely/acpicid.patch .
I saw one more change needed to use on FreeBSD 6.2-RELEASE.
