I realize you guys are probably far down this road in the design process, but FWIW: This is a major motivation for the reason that the IOQ stuff I posted a while back used strings for device identification instead of a fixed length, centrally managed namespace like PCI vendor/dev-id. Then you can just name your device something reasonably unique (e.g. "qumranet::veth", or "ibm-pvirt-clock").
(I realize that if you are going to do PCI, you need to make it PCI-like. But I think using PCI in the first place is probably the wrong direction. IMHO, there's really not a lot of reason to be constrained by a hardware specification once you decide to go PV. This is even more true if you want to support as many platforms as possible (i.e. platforms that don't have PCI natively).
