I2C wants an i2c-proc module, but I can't find where to config it. Something like this happens when I run sensors:

/proc/sys/dev/sensors/chips or /proc/bus/i2c unreadable; Make sure you have done 'modprobe i2c-proc'!

There was an i2c-proc module with lm_sensors 2.7.0. What am I missing?

lm_sensors uses sysfs now. Not proc. Sensors hasn't been updated. You'll have to use cat.

It seems that by trial and error I figured it out. There's a i2c-dev module that I have to load first, then via686a, then i2c-isa. This order is different than with lm_sensors under 2.4 kernels. Also, the i2c-viapro was required before, but now it doesn't seem to do anything.

Thanks for helping,
