The llvm backend hasn't been tested much on Cayman, so probably some of the Cayman specific features aren't working correctly. Could you set the environment variable R600_DUMP_SHADERS=1 and then post the debug output from compiz and minecraft?

It seems alu instruction 0x86 RECIP_IEEE is emitted in a single slot, though IIRC it should be at least on three slots x-z.
