Hi Rob,
This should be possible, especially since you only need one card for
actual graphics display.  Try this:

* Remove the card that you will use for GPU computing.
* Get graphics setup properly on the other card.
* Then get Xorg to generate an xorg.conf for you:
  sudo Xorg -configure
  cp ~/xorg.conf.new /etc/X11/.
* Put the GPU compute card back in
* Load the drivers required for the GPU compute card

Sounds like a fun project, maybe we need a linux demo and trouble
shooting workshop soon.
