Does it make a difference if you use a BoundMetaData for the identity
classes? You can still use a DynamicMetaData for the other classes?

I'm not too sure on TG startup myself, but this code is called from
start_extension. In any case, when the class is imported in saprovider
via turbogears.util.load_class - I thought module-level code in
model.py would be executed (a simple experiment verfied this).
What do you have in app.cfg for identity.saprovider.model.* ?

What does fetchClass do?
