Make Custom Background an Object Page

We want to move Appearance->Background so that it is on the main menu, here is the code I can up with but doesn’t seem to be working.

//=======================================================
//	Move WordPress Custom Background page
//=======================================================
function theme_admin_menu() {
	global $custom_background;

	if ( ! current_user_can('edit_theme_background') )
		return;

	remove_action( 'admin_menu', array( $custom_background, 'custom_background' ) );

	if ( current_theme_supports( 'custom-background' ) && is_admin() ) {
		$args = get_theme_support( 'custom-background' );
		require_once( ABSPATH . 'wp-admin/custom-background.php' );
		$custom_background = new Custom_Background( $args[0]['admin-head-callback'], $args[0]['admin-preview-callback'] );

		remove_submenu_page( 'themes.php', 'custom-background' );

		$custom_background->page = $page = add_object_page(__('Background'), __('Background'), 'edit_theme_background', 'custom-background', array(&$custom_background, 'admin_page'));

		add_action("load-$page", array(&$custom_background, 'admin_load'));
		add_action("load-$page", array(&$custom_background, 'take_action'), 49);
		add_action("load-$page", array(&$custom_background, 'handle_upload'), 49);

		if ( isset( $_REQUEST['context'] ) && $_REQUEST['context'] == 'custom-background' ) {
			add_filter( 'attachment_fields_to_edit', array( $custom_background, 'attachment_fields_to_edit' ), 10, 2 );
			add_filter( 'media_upload_tabs', array( $custom_background, 'filter_upload_tabs' ) );
			add_filter( 'media_upload_mime_type_links', '__return_empty_array' );
		}

		if ( $custom_background->admin_header_callback )
			add_action("admin_head-$page", $custom_background->admin_header_callback, 51);
	}
}

// Finally we add our hook function
add_action( 'wp_loaded', 'theme_admin_menu', 20 );
