Without doing any tests myself, this looks fine to me.
(Which of course doesn't mean anything.)

My only comment for now is that the line

         \ifcsname bbl@l@exceptions@#1\endcsname

should be better written without assuming eTeX:

         \expandafter\ifx\csname bbl@l@exceptions@#1\endcsname\relax\else

I believe this should be integrated into the LaTeX/babel kernel, but we've still got the problem that the babel test suite has not yet been integrated into the 2e SVN repository.

Is there any way around this impasse?
