There is...  It's called MergedFB and works on dualhead R200 radeon
cards (upto, and including, the 9200).  It requires Xorg 6.8.1 or newer,
and 3D support requires the radeon drm kernel module (which is not
nearly up-to-date in DragonFly, but it works).

There is also beta support for r300 and X400 Radeon cards which will
hopefully be merged into Mesa shortly.
