Over the last couple of weeks my co-worker Craig Pierce and I have been working on SCCM sp1 rc1 and rc2. A tip that we learned for looking at the AMT logs and watching them update real time was to use the trace32.exe tool. craig discusses this more in his post @ http://communities.intel.com/message/4343 . I can't tell you how helpful this was as we were provisioning, unprovisioning and using the Inband OOB import tool. The log also showed us the UUID which was important if you are trying to validate that it is indeed the right box sending hello packets.
Here's a couple links for more information:

I will be posting more of my experience with SCCM SP1 and different OEM hardware over the coming weeks.
