IMO you are trying to use the role system for something it wasn't
designed for: Dynamically asigned roles. Drupal roles are always static.

Nothing. You probably need to rebuild the user's menu to get your
changed permisions to "take".

Since rebuilding the menu is a costly operation (in Drupal5) I am not
too excited about dynamically assigned roles.
