I have a Rails 3 app with authentication setup using Devise with the registerable module enabled.
I want to have new users who sign up using our outside register form to use the full Devise registerable module, which is happening now.
However, I also want the admin user to be able to create new users directly, bypassing (I think) Devise's registerable module.
With registerable disabled, my standard UsersController works as I want it to for the admin user, just like any other Rail scaffold. However, now new users can't register on their own.
With registerable enabled, my standard UsersController is never called for the new user action (calling Devise::RegistrationsController instead), and my CRUD actions don't seem to work at all (I get dumped back onto my root page with no new user created and no 
flash message). Here's the log from the request:

... but I am able to register new users through the outside form.
How can I get both of these methods to work together, such that my admin user can manually create new users and guest users can register on their own?
I have my Users controller setup for standard CRUD:
class UsersController < ApplicationController
  load_and_authorize_resource
  def index
    @users = User.where("id NOT IN (?)", current_user.id) # don't display the current user in the users list; go to account management to edit current user details
  end
  def new
    @user = User.new
  end
  def create
    @user = User.new(params[:user])
    if @user.save
      flash[:notice] = "#{ @user.email } created."
      redirect_to users_path
    else
      render :action => 'new'
    end
  end
  def edit
  end
  def update
    params[:user].delete(:password) if params[:user][:password].blank?
    params[:user].delete(:password_confirmation) if params[:user][:password].blank? and params[:user][:password_confirmation].blank?
    if @user.update_attributes(params[:user])
      flash[:notice] = "Successfully updated User."
      redirect_to users_path
    else
      render :action => 'edit'
    end
  end
  def delete
  end
  def destroy
    redirect_to users_path and return if params[:cancel]
    if @user.destroy
      flash[:notice] = "#{ @user.email } deleted."
      redirect_to users_path
    end
  end
end
And my routes setup as follows:
TestApp::Application.routes.draw do
  devise_for :users
  devise_scope :user do
    get "/login", :to => "devise/sessions#new", :as => :new_user_session
    get "/logout", :to => "devise/sessions#destroy", :as => :destroy_user_session
  end
  resources :users do
    get :delete, :on => :member
  end
  authenticate :user do
    root :to => "application#index"
  end
  root :to => "devise/session#new"
end
