Depends on the video driver, but have you tried xrandr to set the
displays?  It's manual, but if you're driver supports it then you just
run it during or after X has started.  I used to do this with my laptop
though GNOME now supports a GUI interface for doing this for my Acer
Aspire (Intel graphics chips).  

I know Intel video drivers support xrandr.  I think nVidia does. Not
sure about ATI.
