I think this separation is artificial.  From both the guest's view and 
the user's view, there's no difference between qemu ioapic and kvm 
ioapic (modulo bugs).  To me this indicates they're the same device.

We'll have the same problem with vhost-net, only there the duplication 
will be much greater if we split the implementation.
