In theory a 'DisplaySize' entry in the monitor section of your xorg.conf
file should do it (see xorg.conf(1))

However I tried it myself a couple of days ago on my Debian Etch
system:
    Section "Monitor"
            Identifier      "Generic Monitor"
            Option          "DPMS"
            DisplaySize     230 140
    EndSection

and couldn't get it to work:
    screen #0:
      print screen:    no
      dimensions:    1280x768 pixels (339x203 millimeters)
      resolution:    96x96 dots per inch

Let me know if you have better luck...

If anyone has any idea what might be going wrong, please let me know....
