Well, does any SMP board map anything into the local APIC space? After
saying there a real APIC there??? Now *THAT* is completely unsafe. How
is that supposed to work when there actually is an APIC-equipped CPU put
in?
Poking unoccupied space leads to bus error exceptions for certain archs
but I can't actually recall existence of such events for i386...
