Any way to find out whether it is supported before I sink too much
more time in spinning my wheels? :)

Shouldn't sensors-detect also probe the I2C bus? I may be
misunderstanding the documentation, but how else do you test if I2C
stuff is working? (In any case, my setup didn't detect anything either way)

I built new rpms for i2c-2.7.0 and lm_sensors-2.7.0. I then did a
clean install of the RPMs (Note I am running under RH8.0/Linux 2.4.20
with I2C compiled as a module). Is there anything else I should be
doing here?

Is there any way I can be helpful in pushing support forward for the
ASB100 chip? I am not a device-driver programmer but I can help alpha
or beta test :)

Thanks again for your help.
