The 'radeon' driver manpage mentions an option called "PanelSize",
which might be helpful if the X server is truly not correctly
detecting the display size (which seems unlikely).

Looking through the X.org log file should tell you what the server
thinks it's dealing with. E.g.,

  $grep -n -A5 'EDID data from the display' /var/log/Xorg.0.log
  507:(II) RADEON(0): EDID data from the display on port 1 ----------------------
  508-(II) RADEON(0): Manufacturer: APP  Model: 9c21  Serial#: 16843009
  509-(II) RADEON(0): Year: 2002  Week: 5
  510-(II) RADEON(0): EDID Version: 1.3
  511-(II) RADEON(0): Digital Display Input
  512-(II) RADEON(0): Max H-Image Size [cm]: horiz.: 32  vert.: 22

There's more in the log file than that (like screen dimensions,
supported video modes, etc.), but you get the idea.

Have you given X a chance to configure itself. Maybe it'll "just
work". Try `X -configure` as root, which should result in an
Xorg.conf.new in /root.
