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?
