Well, the lm80 driver hasn't been ported to Linux 2.6 yet, so you'll
have to wait. If you are brave, you can port it yourself. I wrote a
guide on how to do this, which should be part of Linux 2.6
Documentation/i2c directory someday (but isn't yet either). I can send
it to you if you want.

As for the via686a, it has been reported that it has to be loaded before
other i2c drivers, or it fails detecting devices. I've experienced this
myself. I've not yet investigated why it behaves that way (mainly
because the via686a chipset I have isn't wired for proper input
measurements). Again, feel free to help if you can, or you'll have to
wait until we find a solution.
