I run a monitorless combined front/backend. Actually there is a tv
attached via a home made vga to rgbhv converter cable but as far as the
video card is concerned, nothing is attached. Attached below is my
xorg.conf which runs my custom modeline but you could easily modify it
to use your supported modes quite easily.
