Yupp, mesa-8.x is not that "llvm-3.2 friendly", but with the list of
patches I could compile and run it!

Unfortunately, a self-compiled mesa-9.x (master/9.0/gles3) from GIT
breaks here compiz on Ubuntu/precise.
Unity-2D is OK.
So, you keep the original Linux graphics stack shipped with your
distro or you are alone.
