[SOLVED] OpenCL AMD/Radeon (amdstream) Missing Device Without X

So I bought an AMD 6950 to do faster computing, since it seemed like the cheapest way to get a lot of stream processors. Unfortunately, I am having trouble getting the drivers to work. I have installed amdstream and libopencl from AUR.

If X is running then the screen freezes (presumably because the video card is being shared), but if X isn't running, /opt/amdstream/bin/clinfo hangs, and so do any opencl programs that attempt to get a list of available platforms. Strace seems to indicate that the program is attempting to connect to X:

Any thoughts on this?

Edit:
Hanging was caused by iptables, I was blocking 127.0.0.1, which prevented ./clinfo from failing to connect to X, and thus the hang.

Now the problem is that without X, my GPU doesn't show up, just my CPU:

Apparently X has to be running which is a little lame:
