Rails 3.0 Engine - Run Code in ActionController

I am updating my Rails plugin to be an engine that works with the latest version 3.0RC1, and I am having trouble finding the best (and most correct) extension method ActionController. I saw this post from DHH and this question is here on SO, but my question is more about how to properly call the code in ActionController.

For example, I need to call the following in my kernel controller:

class ApplicationController < ActionController::Base
  helper :all

  before_filter :require_one_user
  after_filter :store_location

  private
    def require_one_user
      # Code goes here
    end

    def store_location
      # Code goes here
    end
end

I know how to enable my two private functions correctly, but I cannot find a way to call it correctly helper, before_filterand after_filter.
