Do you have an nVidia card that works on real hardware? Last I checked
was a while ago, but they weren't working at the time (IIRC it was
something to do with PCIe addressing, but it was a hardware limitation
so I don't remember exactly how it all fits together).
If they work then I'm happy to flip them on.
