I'm no expert/didn't try only know about this by reading.
But as far as I know:
This feature is not provided by your video card, but provided by your motherboard's or CPU's (not sure which one) IOMMU and by software.
See http://wiki.xensource.com/xenwiki/XenVGAPassthrough for more info.

(If I told something wrong, correct me !)
    i have some questions to ask you.
    in YouTube.com, i saw the video about XenVirtualization VGA Passthrouth Playing 3D FPS Games.
    using the video card "Geforce 8400 GS " ,the video implement " XenVirtualization VGA Passthrouth ".my question is that :
    1  can other video card (e.g. Geforce 9300 GE that is used by me.) implement" XenVirtualization VGA Passthrouth "?
    2  if the video card is used by VM in Xen , the host OS destop can't display. Is it right?
    3  if in my PC has 2 video cards(one is Geforce 9300 and the other is onboard video card) ,the 9300 video card is used by VM and the onboard video card is used by host. can it implement?
     thanks a lot.
