Yes, of course. I never wanted to use a guessed and not documented
value. I only wanted the temperature reading to be plausible.

They have the same CPU model ID:

# grep model /proc/cpuinfo
model : 28
model name : Intel(R) Atom(TM) CPU N270 @ 1.60GHz

# grep model /proc/cpuinfo
model : 28
model name : Intel(R) Atom(TM) CPU 330 @ 1.60GHz

I would like to propose to use the patch as it is. It's the best
version we ever had.

Carsten.
