Would be great if the archlinux folks would submit their patches upstream,
if there are any.

I have seen that with a number of boards. So far I have no idea what is going on.
My best guess is that the pins are not really connected, and that PECI Agent 0
is the real CPU temperature. Another guess is that the sensor type is not
configured correctly. I might create a test version of the driver where
it can be set to check that possibility.
