Hi Tim,

Here is the current status for the different vendors.

Nvidia graphic cards don't work as primaries, there are some issue
with the bios rexecution.
Nvidia cards should work as a seconday display adapter side by side
with the cirrus.

So far ATI doesn't support vt-d.

Intel graphic card only works as a primary.
