Hi there. I have a couple of mining rigs working well, but on one of my rigs, it seems that CGMiner is confusing the video cards.
I have confirmed the same problem, and it even happens in cgminer 2.97 all the way to cgminer 3.11.
I am running 2x7950s here
The problem is, say GPU 1 is overheating, it will downclock GPU 0, and not help the situation, because its slowing down the wrong GPU.
Here is a screenshot of this issue in action

You can see clearly GPU0 is in use (from the temperature), even though it thinks GPU1 is in use. I have tried gpu-map and gpu-reorder and could not seem to solve the problem.
I am running Catalyst 13.1
