I don't think this error has anything to do with Mesa or the r600 driver.  This
error message comes from the Cg compiler.  It's saying that the shader is
trying to do something that the Cg compiler can't handle on this driver.  Cg is
the shading language from NVIDIA, and it's compiler is completely external to
the driver.  The game is trying to do something that the driver can't do.
