How is this not x86-pc specific? All you're doing is creating two different 
machines, one with an APIC and one without.  In principle this is no different 
to what we have with pc v.s. isapc.

If you want machine properties (to avoid having to enumerate all the available 
machine variants) then these properties should be machine specific.

Incidentally, you patch appears to allow creation of a machine with a cpu that 
claims to have an APIC, but without an APIC present. Is that intentional?
