I'm using the release version of LLVM 3.4 and ran the game with your debug option: 'R600_DEBUG=ps,vs ./ADVGame.sh > ADVGame_R600_DEBUG.log 1>&2' Since I could not upload the file here (to big) I stored it on my server: http://shadowice.org/~flocke/linux/misc/ADVGame_R600_DEBUG.log I hope this helps a little, I can try to provide additional information if needed.
