On VIA VB7002 acpitz obviously does not work so I can not compare. I
guess BIOS does not support the temperature reading since there is no
temperature readout in BIOS.

acpitz-virtual-0
Adapter: Virtual device
temp1: -247.7 C (crit = +140.0 C)

via-cputemp-isa-0000
Adapter: ISA adapter
Core 0: +27.0 C

Is there a way to reset the CPU temperature calibration to the factory
default?

There should be among those registers we dumped
for Harald. He now has a good and a bad case to
look at - he also has access to the msr magic numbers.
