Yeah, you can probably do changes similar to the ones I made in other drivers to just restrict support to one PCI domain for those or you can update them if you really care.

I sent a patch to the list about 2 weeks ago for vmware.
I don't have access to openchrome and haven't looked at it.
tdfx and xgi are a bit more "special" and hopefully someone else can take care of those since it's out of my real expertise.

wrt other drivers, I did the minimum necessary change with the least risk (from my perspective) rather than more sweeping changes to utilize libpci.  This should minimize risk and let someone else go through and update the driver as a whole if they care.

As mentioned earlier, I need to go through and make sure none of the drivers are using removed functions since that won't cause an actual build failure.
