Thanks for the suggestion. I was able to get it working with the following:

Section "Device"
       Identifier      "Radeon Mobility M6"
       Driver          "radeon"
       VideoRam        16384
       BusID           "PCI:01:00:00"
       Option          "dpms"                  "on"
       Option          "CloneHSync"            "31.5-80"
       Option          "CloneVRefresh"         "56-76"
       Option          "CloneMode"             "1600x1200"
       Option          "PanelOff"              "true"
EndSection
