As the person asking for help here, it's your job to make complete
answers, that don't require me to "read as". I am no seer.

It looks like you are missing a very important point here. You are the
one asking for help. I am the one providing the help FOR FREE, on my
SPARE TIME. The least you can do is make it easy for me, provide
correct answers to my questions, and assist as much as you can, instead
of waiting for me to do all the work based on incomplete information.

Your question is NOT very clear. If it were, it would have been
answered already. First of all you omitted to tell us that you were
migrating from a different system where the vt1211 was working. At this
point I still don't know what was that system. 2.4 kernel? Or 2.6 with
Lars Ekman's unofficial driver?

Why did you upgrade your system if it was working?

Our main point with that change, as you can easily imagine, was to
gratuitously break as many user systems as possible. And make them
angry after us, to trigger many complaints on this list. If it works
well, we'll make sure to do it again with every new kernel version,
it'll be great fun.

(Seriously, if you're not happy with what we do, feel tree to join the
development team and show us how to make things better. I'm eager to
improve. There's plenty of work for everyone interested.)

Start from etc/sensors.conf.eg in lm_sensors 2.10.1, as I suggested
already. Then read the vt1211 driver documentation
(Documentation/hwmon/vt1211 in the kernel tree), which Juerg Haefliger
was nice enough to update and extend. Most probably, you don't actually
need to change the formula, just replace "compute temp3" by "compute
