I suggested that in email too, but looking closer, I think the MAXCPU
needs to be increased because the cpu number uses the apic_id. Or could
that be changed with a logical CPU to APIC ID lookup?
Isn't the APIC IDs programmable? not that I am suggesting that, I
can think of headaches of all the places (like interrupt tables)
where it needs to be changed, not to mention the worry that the
lower APIC IDs were assigned to IOAPICs.
