I can think of a two advantages:

- the device can deliver interrupts to the guest when something is 
completed (I don't know how useful this is to a 3D device)
- the guest can autodetect the presence of the device by means of a PCI 
ID.  This means that if the guest driver is eventually included in the 
OS (which is possible in Linux), then the driver will be loaded 
automatically by the OS.
