Haven't we already confirmed that it *isn't* just an ioapic accelerator

We haven't confirmed it. Both implement the same spec, and if you
can't migrate between them, one of them has a bug (for example, qemu
ioapic doesn't implement polarity - but it's still just a bug).
Are you saying that HW spec (that only describes software visible behavior)
completely defines implementation? No other internal state is needed
that may be done differently by different implementations?
