I have an identical setup and I got it to work properly at 450 Mhz by applying thermal grease (available at Radio Shack) to the CPU and heatsink. Took all of 15 minutes excluding the trip to the store. This fixed the buildworld problem. I now run healthd to monitor the temperature of my CPU. If you are not familiar with anti-static handing procedures, DON"T TRY THIS! If you are, note that you want a THIN coat on both surfaces. Also, make sure your heatsink fan is running properly! R.
