I'm also not clear if the i²c mapping is always the same. Certainly this
is a problem on Moorestown/Oaktrail in some cases.

Interesting.

Importing the code seems reasonable. KeithP didn't want it shared when I
asked him, but importing it and having the same code in many areas is the
first step to sharing anyway.
