Hi all and happy new year!

I promised holiday, but CDMA works here. ;)

Yes because you have on your board another chip, which is actually used -
W83793. Just modprobe w83793 driver, and report if it is OK. And please use the
lm-sensors version 2.10.1 which has support for this chip, the sensors-detect
from 2.10.1 should find it.

Please report back the output of sensors command, and dont forget to update your
sensors.conf
