I'm glad it works so well :) Just to make sure I understand it well, the
it87 was on a completely different system, right?

We suspected that the LM90 would be found on a number of motherboards,
so we included detection for it (as well as half a dozen of similar
chips) to sensors-detect. Each time someone reports he/she needs one of
these "to-be-written" drivers, we write the driver (or add support to an
existing driver). This make it easy to support only chips that are
really used (thus keeping drivers small), while still letting people
know that we are able to support some other ones if needed.

OK, good to know. Since your system was working OK with 2.8.0, I was
surprised that you would have problems with 2.8.1. Although 2.8.1 has
the same compatibility issues as 2.8.0 does, once it has been solved for
2.8.0, there's no reason it wouldn't work with subsequent versions.
Thanks a lot for your report, it's really great to have positive
feedback from times to times ;)
