@bryce, I'm really sorry I didn't report it sooner. I'd been fiddling with a bunch of other stuff (compiling from git etc.) so I figured it was just me. Soon after I managed to compile the 3D R600 branch and I've been using that since. It was only when I saw the comment in the Karmic forums that I realized it wasn't something I'd done.
