How are you setting the default? If you specify the 'default' argument for
the Field object, it should enter that default even if you set
writable=False (at least it does for me, though I haven't tested it
specifically on the auth_user table). Can you show some of your code?

Depending on what you need to do, I think you should be able to alter the
auth form before it gets passed on to the view. In your user() function, do
something like this:
def user():
form=auth() # This creates the appropriate auth form, depending on
request.args.
if request.args and request.args(0)=='register':
# code to alter the registration form
return dict(form=form)
Note, if you want to do something after registration form validation but
before the form is accepted, you can also specify
auth.settings.register_onvalidation (see
http://web2py.com/book/default/chapter/08#Settings-and-Messages).
