Thanks all for your replys :-)

I upgrade to Linux 2.6.25.4 and lm-sensors 3.0.2-1 and now I can get  
values from LM93 chip, example output:

===============================================================

in13:        +1.19 V  (min =  +0.89 V, max =  +1.09 V)
in14:        +0.97 V  (min =  +0.89 V, max =  +1.09 V)
in15:        +0.30 V  (min =  +0.07 V, max =  +0.54 V)
in16:        +3.41 V  (min =  +2.97 V, max =  +3.63 V)

cpu0_vid:   +1.088 V

===============================================================

But I think that this chipset is not fully supported in lm-sensors  
already, I do not know what temperatures refences temp1, temp2 and  
temp3 params.. maybe physical processors and mother board.. I will  
ask in the m-sensors mailing list..

There's no way to get thermal information information via ACPI in  
this motherboard? I get this error when running "acpi":

# modprobe thermal
# acpi --thermal
No support for device type: thermal
