Same problem on my machine with the Hardy Heron install CD. The graphical output is not shown if the TFT is connected to the DVI channel (blank screen). The log output of /var/log/Xorg.0.log looks OK and if I connect the display to VGA everything is OK. No changes if I try to set the Option "CrtcNumber" ... I get an output on DVI when I set Option "Dualhead" (but then the left part of the combined screen is missing).
