I have a problem making sensors to work with my Via chipset
When issuing 'modprobe via686a' after the rest of the relevant
modprobe's I get an error message indicating that I should use
the force_addr argument.
When "guessing" the correct address - this error message
disappears, but /proc/sys/dev/sensors/chips is empty resulting
in 'No sensors found!".
I have tried the addresses 0xd800, 0xd000 and 0xd400.
By an error I tried 0xd00 and now /proc/sys/dev/sensors/chips
did contain the via686a chip - but sensors came out with total
rubbish.
So in short my question is (assuming that it is not an other
error): how do I determine the correct address for modprobe
via686a ?

These modprobes work:
modprobe i2c-core
modprobe i2c-isa
modprobe i2c-dev
modprobe i2c-proc
modprobe i2c-viapro
But when issuing
modprobe via686a
I get following messages:
