Sorry to revive such an old topic, but your understanding is incorrect. 
 There are open source 3D drivers for everything up to, and including, 
the Radeon X850 in the Mesa source tree (and Xorg 7.1, possibly 
earlier).  Anything newer than the Radeon 9250 is still considered 
relatively experimental, but it is certainly functional enough of linux 
and FreeBSD to play a couple rounds of doom3 or quake4.

My guess is that there just hasn't been a recent update to the radeon 
drm code in DragonFly.
