Excellent question.  I've nabbed the latest release for the system and  I'll
slap it in there and take a look.

>> mpbios: bus 1 is type ISA
>> mpbios: bus 0 is type PCI
>> ioapic0 at mainbus0 apid 16 (I/O APIC)
>> ioapic0: pa 0xfec00000, version 11, 16 pins
>> ioapic0: misconfigured as apic 0
>> ioapic0: can't remap to apid 16
