Not that I know

Maybe, but I guess it depends on the cards. These are not "normal" PCI devices,
as they also map some ISA-space registers to be compatible with plain VGA.
Some can work without theses, some can't ...

I'm almost sure this won't work, because of the VGA registers which are
in ISA space. If you can use a VGA card in a domU, I think is has to be
another card than the one used by BIOS
