Looks pretty good.  I will add it to kernel sources.

Did you investigate the Linux I2C implementation?  I never did, but
perhaps it would be worthwhile to make this look like that at least
to an application.

That is fine.  I could never make it work either.  I have had some
discussions with others about this, but no solution yet.

The challenge is some devices need this address, others don't.  What
you have seems fine.  After we use it for a while maybe we can find
something better.
