On the vanilla xen, it almost works (with quirks) as a secondary adaptor (i.e. gfx_passthrough = 0). This is after a few hours "testing" out both setups (patch and vanilla) using Portal 2. The game did crash once every 20 minutes or so using the vanilla xen, but was absolutely stable using the patch. 3DMark05 gave a score of about 18400 in both setups, which seem congruent with the scores from this graphics chip. So IMHO, if anybody wants to do graphics passthrough, definitely go for an ATI card.
