Someone else is working on pci passthrough for GPLPV. It might be ready
for some testing shortly.

I've never used pci passthrough at all (well... not since xen 2.0
anyway) but from discussions I've had it appears that once PV drivers
become present, Xen (or qemu at least) assumes that the PV drivers will
handle the passthrough function instead of qemu. That may be incorrect
though... hopefully someone else can enlighten me.
