FreeBSD itself doesn't enforce this, we use whatever CPUs we find in the table 
and we don't actually bother reading the family/model/etc. from the APs at 
all.  Assuming this is a non-ancient computer and non-ancient FreeBSD (5.2 or 
later) then FreeBSD isn't using the MP Table at all but the ACPI MADT table 
(available via acpidump -t).
