Please have a look at the ati readme in the xfree86 docs.

My device section looks like this:

Section "Device"
  BoardName    "Radeon LX"
  BusID        "1:0:0"
  Driver       "radeon"
  Identifier   "Device[0]"
  Option        "PanelOff" "true"
  Option        "AGPFastWrite" "true"
  Option        "AGPMode" "4"
  Option        "CloneVRefresh" "70-80"
  Option        "CloneHSync" "30-98"
  Option        "MonitorLayout" "CRT"
  Option        "CloneDisplay"  "true"
  Screen       0
  Option       "Rotate" "off"
  VendorName   "ATI"
EndSection

As you can see, my A31p displays the standard resolution (no CloneMode 
option) only on the external display (CRT), i think you can play with 
the options to setup your needs.

I don't know if you need xinerama, i only use one display at a time.
