This adds the r600 KMS + CS support to the Linux kernel. The r600 TTM support is quite basic and still needs more work esp around using interrupts, but the polled fencing should work okay for now. Also currently TTM is using memcpy to do VRAM moves, the code is here to use a 3D blit to do this, but isn't fully debugged yet.
