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.
