This is exactly the symptom described in the blog post I sent you to.

Did you read it?

You don't really have a DS162x chip on your system, do you? The output
above is rather suspicious. Does the temperature value ever changes?

This chip is very difficult to detect and misdetections are very
frequent. We should probably even disable it altogether. So if that's
all you had with kernel 2.6.30.4, it hardly qualifies as "worked".

I don't know anything about this specific issue, sorry.
