Salut,

You probably need a more recent radeon driver. Unfortunatly we're
still blocked by the bug that prevents "zaphod" dual head more from
working in current X.Org sources. 

Your options are:

- try the "ChipId" option in xorg.conf to force the radeon driver to
  attach to the card it doesn't know about (might lockup the machine)

- get the latest (6.14.2) xf86-video-ati from X.Org, and build it.
