mmm... perhaps is not so a big problem.
When the user will have the ADO.NET exception he will try to file a JIRA or
a question in nhusers and we can help him.
Another possible thing to do is in releasenotes...
I think I have already fixed the last problem with the default-driver set by
the dialect, so we can invite all users to remove the the set of
connection.driver_class and trust in NH (at least for MsSQL).

Thoughts ?
