We definitely want a pc machine type and a kvm-pc machine type.  The 
later would change the default cpu to kvm64 and would use the in-kernel 
apic.

If we want to support non in-kernel apic for debugging, I'd suggest that 
we support it by introducing a third machine type: kvm-pc-debug.

When we complete the qdev conversion of pc, different machine types are 
just config files so it seems like a reasonable thing to do.
