Looks like they are using PECI agent 0 as monitoring source. Odd, though, that 0x150 
reads zero but reports -60 degrees C. Is that fluctuating ?

Also, can you dump registers 0x100, 0x200, 0x300, and 0x621 to 0x626 ? Those registers
define the mapping from temperature sources to registers (0x152 was wrong; should have said 0x622).

Thanks,
Guenter
