Any distro which has a relatively recent mesa, and which packages xf86-video-freedreno should work. Please feel free to add more, update status, add links to instructions, etc.
NOTE: please feel free to make updates/additions to the wiki, add pages for your particular device that you have (or are trying to use) freedreno on, etc. A wiki is a community effort. Don't vandalize. If you have a question, ask on #freedreno IRC channel on freenode.
