I bumped it up to 20% and the Mh/s increased to 100. So it would appear that the CPU usage is tied to the hashrate of poclbm.

Okay so as an update. I was able to create a new user, run guiminer under that user which also ran poclbm. I then throttled the user account to 5% CPU....and watched my miners only pull in 50 Mh/s

Absolutely brilliant! This got me thinking and googling. It appears that you can throttle CPU usage by SID (user) in Windows 7 http://technet.microsoft.com/en-us/library/ff384148%28WS.10%29.aspx
You can run a process, say guiminer (and maybe poclbm?) as a different user: http://www.sevenforums.com/tutorials/419-run-different-user.html
So it should be possible to run the miner under a different id, then then throttle the cpu usage of that user. I haven't tried this out yet - The family and I are about to go to the circus, but I thought I'd throw my thoughts out to the brain trust and see what they come up with. Otherwise, i'll dork around with it this afternoon.

Is there any way to write a program that fakes a third core on a dual core CPU that runs at like 10 Mhz (1/300 of the power of a real core) and set the affinity of the miner to it?

Because even if it's possible it would be easier to just reverse engineer ATI's stream SDK and fix the bug...
OK, go on!
