I agree that pci interface isn't ideal, the advantage is that platforms
that do support pci don't have to implement a virtualized bus, and pci
is PnP device. This was the motivation behind using it, especially for
Windows.

Now that more platforms are joining the KVM wagon, we should define a
common bus. PCI was a overkill anyway - its irq are shared and we don't
have to use its io/mmio areas.

Do you guys have something to start with?
