Thanks for your reply.
the sensors.conf I'm currently using is provided by Tyan, so this seems to be ok. One major difference that I can see: I don't have compute statements for the CPU temperatures. If I use your config, I get 7.8°C :-)
So there is definitely some difference in our hardware environment. OTOH with the "right" compute statement the problem seems fixable.
BTW: there is another hwmon chip on the board, a w83627hf. Up to 2.6.21 this was managed by the w83781d driver, too. Now I use the w83627hf driver (on the isa bus). No problem with that part.
