Re: [Xen-users] [Xen-devel] [REQUEST] Request for Xen Users to Attempt Jean David Techer's Xen 4.2-unstable VGA Passthrough Documentation
Hi Pasi,
I can confirm that their GPU Passthrough works with consumer models, they visited my college and presented a 30 minute demonstration video where they acknowledged this.
Wei stated that XenClient ahs a "customized ATI component", and I am quite certain he is aware our discussion is about consumer models.
XenClient comes with XenDesktop, they market to the on-the-go businessman so it was designed with laptops in mind, but I am quite sure it would run on a tower.

Yes it's available on the xen-devel mailinglist archives,
and iirc also on the xen vga passthru wiki page.
I think the link/url was already posted to this thread once.

Some ATI cards work as *secondary* without extra patches,
but passing them as *primary* requires a patch to make the
ATI specific VBIOS stuff work properly.
