On my T40 I had to add the extern_disp and intern_disp lines to my 
XF86Config file. My Device section looks like this:

Section "Device"
  Identifier "Videocard0"
  Driver "radeon"
  VendorName "Videocard vendor"
  BoardName "ATI Radeon Mobility M6"
  VideoRam 16384
  Option "extern_disp"
  Option "intern_disp"
EndSection

Then pressing Fn+F7 once or twice gets the external monitor 
(specifically, a projector) to see things. Hope this helps.
