First we had plans only for plain PCI pass through and not VGA device that has some bios unification possible issues. Second, we have it working (also all the code was sent to the list) but there's quick an effort to be done in order to merge it into mainline. We do want it to happen but we have some other issues on our plait. Nevertheless, if one wants to push it on we'll be happy to assist.
