I can see the device though in /sys/bus/pci/drivers/pci-stub/ and "lspci -v -s 0:07:0.1" reports the driver in use as pci-stub.

It just hides devices, but does not do anything else? Ahh, n/m. QEMU uses those devices to do the PCI emulation along with pass-through for the devices. Obviously it only works for HVM guests.
