I have the same problem with an Tyan Tempest i5100X (S5375) where I want to
assign a AVM B1 ISDN Card to a DomU

To pass-through the ISDN Controller (01:01.0) to my PV-DomU I have to
pass-through also the graphic card (01:00.0).

The board has only 2 32-bit slots and both are on the same PCI-bus (0000:01)
where also the internal graphic card is assigned to. This graphic card is
connected to the BMC, so I do not want to use an extra card.
