Here is the xorg.conf that did total and absolute magic for me:

Section "Device"
         Identifier  "Videocard0"
         Driver      "i810"
         Option "Clone" "yes"
         Option "MonitorLayout" "CRT,LFP"
         Option "DevicePresence" "yes"
EndSection

Not sure if it will work with your display card, but it is a fairly 
generic setting, so it should.
