Well, two suggestions here:

1. From the radeon man page:
Option "ReverseDDC" "boolean"
When BIOS connector informations aren't available, use this
option to reverse the mapping of the 2 main DDC ports. Use  this
if the X serve obviously detects the wrong display for each
connector. This is typically needed on the Radeon 9600  cards
bundled with Apple G5s. The default is off.

2. Try adding
Option "MergedFB" "false"
It looks like it's detecting both heads, not monitors attached to
both heads.

If that doesn't work, please let us know. :)
