Yeah, I find it pretty peculiar, too.
The wall wart meaasures a steady +12v DC. I pretty darn sure I didn't hit anything other than the 2 solder points and the one tracer. I talked to one of my buddies who works for the man designing boards & stuff over at Intel and he's gonna take a look at it and tell me what he thinks. One of the few redeeming qualities of working in the Silicon Valley....
