Most Radeon GPU lockups come from Mesa 9.1.7 which is way too old.

Mesa 10.3.2 is available on FreeBSD 10.1 (which is around the corner) if
you build it yourself (the official binary package will remain at Mesa
9.1, because of our Intel driver in FreeBSD 10.0).

Therefore the preferred solution is to upgrade to FreeBSD 10.1 as soon
as it's released or right now if you want to test the release candidates.
