Hmm.  I'll think about how to do this.  Since Peppercon can sell to
other customers, I'm not sure how to tell it's definitely a Supermicro
motherboard.

It can be difficult since there are many permutations and ways OEM
extensions can be handled.  The Supermicro ones are particularly unique
and have a special case.  (And the fact the above motherboard doesn't
even list Supermicro as the vendor makes it more difficult.)

If you're interested in learning, the beginning steps are the files in
libfreeipmi/include/freeipmi/spec/, libfreeipmi/src/spec, and
libfreeipmi/src/util (this is just for sensors, not for SEL
extensions :-).
