Hello, I have been working on VGA-passthrough in the last month. When Xen was at his version 3.5 there was a few patches to make this work for some graphic cards using the patches developed by Han Weidong and posted here (http://lists.xensource.com/archives/html/xen-devel/2009-08/msg01176.html) and the same patches posted file by file are here
