I think they are independent of CPU itself. It usually configures some registers 
in chipsets for default values, like SB-NB bus.

If you cannot see any fetches except those, the CPU is not running or is unable 
to talk to the flash (defective route).

The thermtrip is sw independent so does not play role here.
