Indeed there have been many people doing the same, unfortunately nobody
ever posted a patch which would preserve compatibility with python 2. I
don't know a thing about python but I can't imagine that this is not
possible.

Unfortunately, as long as nobody contributes a patch which makes
py-smbus work for both python version 2 and version 3, I can't apply
it. I don't think it makes sense to break compatibility with one
version to make the other one work.
