Your're right. First, I was confused too, but then Mark pointed me to a patch,
which is never gone into mainline:
http://lists.lm-sensors.org/pipermail/lm-sensors/2005-December/014727.html
Be aware of the different names: m41t00 and m41txx!

Oh, yes. I found it too, but didn't checked it further.

This question, only Mark can unswer, or?
