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...
