Comment(by wad):
I've got one of the motherboards hooked up to the scope, and what I see is
constant switching of CPUSTP# and VDRSLP. Eventually, VCORE goes from
0.8 to 1.2V (VID seems to change at this time), followed by VCORE dropping
to zero slightly later.
The heat sink is properly connected --- the CPU is not running hot.
