How can I skip i2c detection?

Jean,

Here's the i2cdump output.  
I did not run sensors-detect on my target, as perl isn't installed.

Wow, i2cdump runs MUCH faster with those timing changes!

Hi Ben,

Does sensors-detect find an LM82, or an LM83? Or both? Or none?

Could you please provide a dump of your LM82 chip (use i2cdump)? I could
compare with my LM83.

If there really is no way to differenciate between both chips, well,
we'll simply document that fact, and invite LM82 owners to ignore the
two irrelevant temperature channels.

Thanks,
