3.5.1 Gallery problems

In previous versions of WP you were able to save a gallery without actually inserting it into a post. This was handy since it allowed for easy gallery creation that wasn’t part of the core content of your page.

I used to use the following function to retrieve the gallery but unfortunately this no longer works with the revamped gallery functionality since the Save Gallery option is no longer there:

function get_gallery( $post_ID = NULL )
	{
		global $wpdb;

		if( empty( $post_ID ) )
		{
			$post_ID = get_the_ID();
		}

		$gallery = $wpdb->get_results(
			$wpdb->prepare("
				SELECT * FROM ".$wpdb->prefix."posts
				WHERE
				post_parent=%d
				AND
				post_type='attachment'
				AND
				menu_order > 0
				AND
				post_status='inherit'
				AND
				post_mime_type LIKE '%%image%%'
				ORDER BY menu_order ASC", $post_ID
			)
		);

		return $gallery;
	}

Is there any way to retrieve a gallery in a similar fashion with the new gallery functionality?
