Most FreeBSD instructions are also valid for DragonFly but the ttm memory
manager required by the KMS Radeon driver is unstable and thus the
xf86-video-ati driver is still kept to the last non-KMS version by default.

If you want to give it a shot nevertheless, you'll have to check out the
dports repository and compile a new version of xf86-video-ati yourself.

The check
  .if ${DFLYVERSION} < 300751 || !defined(WITH_NEW_XORG)
in the ports Makefile has to be changed to something returning true for the
KMS-aware xf86-video-ati driver to be built.
