My suggestion is use Catalyst 11.7+2.5 OCL drivers (the preview not the beta since they're very unstable). I have 3 cards on a machine and no dummy plugs or crossfire bridges, their mining good. =)

My first inclination would be to re-install the drivers and see if that fixes the issue.

Just a thought.
