I pretty sure I can define some gsoc tasks related to the llvm tgsi backend
if people are interested. One possible option would be the addition of
a 64bit memory model (this will also require some mesa changes).

Basically there is a long todo list, but llvm is NOT easy to get into,
so it maybe better to find some other task.

Hans
