The old-style AMD drivers need an X server running in order to do GPU compute. If you don't have that running, you may well see the error you're encountering. On the other hand, I'm not sure if that device node is sufficient to run an X server against--no experience with that. My understanding is (though I have not tried it) that the newer AMD drivers (based on the open-source kernel driver) do not have this restriction. This may be worth trying though.
