The problem is here. i2c-viapro and via686a are mutually exclusive in
2.6. Remove i2c-viapro from your kernel if you want via686a to work

Note that you may then disable this one too, since it'll be useless
without i2c-viapro.

The conflict is documented on our 2.6 kernel info page:
http://www2.lm-sensors.nu/~lm78/kernel26.html

I admit it would be better to actually fix the problem. Unfortunately I
don't know how to do that myself.
