Start by reading "man 4x radeon" and pay close attention to anything it says
about "MergedFB". Decide if there's any reason you don't want to or can't
use that feature of the driver. If not, you probably want to go that route
to get the performance bonus. Look around on the web for examples.
If you don't end up wanting or being able to use MergedFB then you should
use Xinerama (X's multi-head software). You'll need to enable it with
something like this:
Section "ServerFlags"
Option "Xinerama" "1"
EndSection
Then you'll need to add an additional Screen item to your ServerLayout
section (and specify the relationship between the two screens), then add
additional "Device", "Monitor", and "Screen" sections to the file
describing your second display. Again, there should be a lot of
documentation and examples out there since (as Ted mentioned) this isn't
FreeBSD-specific.
