Can you see if the attached patch works for you?  It works for me,
introduces minimal changes and allows for upgrading BBDB 2 to BBDB 3
without restarting Emacs.  The defvar change in your patch concerns me
because it will miss if the BBDB version changes after the variable is
first assigned.

I'm also going to experiment with eudc-export which also may need to be
updated for BBDB 3 handling.

Longer term I hope to work toward bundling BBDB in Emacs which would
eliminate the need to support multiple versions.
