ah ! thats why i don't remember vgaarbitrator, you moved to x.org
(Old page says xat is what you are working on).
so what about the border case, viz-a-viz
1 graphic card with 2 outputs to be used as a multiseat ?
(both on only 1 pci bus)
Is there any plan to support independent X servers on the same gfx card ?
