This works if you have facebook_auth installed and you already have a `Facebook apps' for logging to your site

    if (variable_get('user_register', 1)) {
        // Users can register themselves.
        return t('<a href="@login">Login</a> or <a href="@fblogin">Facebook ID</a> or <a href="@register">register</a> to post comments', array('@login' => url('user/login', $destination),'@fblogin' => url('facebook', $destination), '@register' => url('user/register', $destination)));
      }
