See: http://www.cs.toronto.edu/~andreslc/xen-gl/ I have a test pkg nearly complete. Also, it may be possible with XF4VNC.
What if I had two graphics cards, could I map one DomU to use a specific card and display it on one screen?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 ...Or could I map one of the DomUs to the main gfx card after dom0 started it and run X session from it?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
There are some reports of the two grapics card approach working. See the first "Cool Configuration" in the Xen WIKI:
