Yeah, this won't map nicely on future chipsets - unless we redefine
Q35_PSEUDO_XXX as VTD_PSEUDO_XXX, or so, and use the same values for all
of them. Or create an unconnected pseudo PCI bus for the chipset devices
that carry the pseudo bus number.

Good, then we are already two ;). Let's get the baseline ready, then we
can discuss extensions like interrupt remapping.
