I think that's a bug in my treatment of MySQL's information schema support.
Are you by any chance using MySQl 5.0.6 or later?

The foreign_key_name_generator predates the convention manager, and sort of
conflicts with it. Right now, the CM's auto_foreign_key_name() method gets
a first shot at naming foreign keys. Only if it returns false does the
foreign_key_name_generator ever get called.
I'm not sure how to resolve this. I'm leaning towards just ditching
foreign_key_name_generator entirely, since the algorithm in
auto_foreign_key_name() is a bit more sane, IMO. Thoughts?

Ignoring foreign_key_name_generator for now, I suggest this: Create your
own custom ConventionManager subclass and override auto_foreign_key_name().
Then give the loader object your custom CM.
