AFAIK Xen doesn't need it, it just wants access to the different PCI
busses. It just needs to uniquely identify a device, the autoconf
index of the parent is enough for this.

.. which, for lack of something better, I use in libpciaccess. If DRM could do the same the problem would go away.

have fun
