I think Vcore is measured from pin 'in1', but it produces 'too' good stable
reading of 1.500 anyway -from day to day. It's not exactly the same what I
can see in bios, but the reading is quite stable there too. The slight
difference (1.494 in bios) _could_ be caused by slightly different current
consumption, maybe? I have tested this both in console, and in a terminal
window under X, both result always in 1.500. Strange? I've tried this so far
in only one computer, maybe the next one will give different figures.

Or am I thinking something in a wrong way again? Below is the output of
'sensors' and piece of sensors.conf.
lm_sensors is version 2.8.7-2, from current FC3 rpm.

Limits of Vcore are based to VID, which equals to 0. Is it a variable that
needs to be se manually in the file, or should it be automatically readable
from somewhere.
