This has been discussed quite often here.
You'll find data file and example on :
I'll try to do a short summary:
With default X server, you can manage this with a two headed
setup, either in xinerama or in two display mode. In both case, with
use fbdev, the behavior of the external output is undefined. So the idea
is to defined two cards, one with fbdev and one without. If you want to
clone your display, you will need to ask xinerama to superpose two
display. In any case, you will loose DRI on both heads.
If you want dri, there exists a hack based on a patch of the radeon
driver. You'll find details on the above address.
At least I can say it works : I used it with openoffice in a conference
last week !
