first of all what are you trying to accomplish?  Dualhead or clone mode?
it sounds like X isn't detecting your monitor properly.  you might try adding:
Option "MonitorLayout" "LVDS, CRT"
to the first device section of your config.  Also please post your log
somewhere.
You might also look through the radeon man page for some help in
understanding what options are available for radeon.
