 The ability to specify attachment IDs in a gallery shortcode isn't new to
 3.5, it just got a handy UI.

 You can grab attachment IDs from a gallery with a snippet like this:
 {{{
 function grab_attachment_ids_from_gallery() {
         global $post;

         $attachment_ids = array();
         $pattern = get_shortcode_regex();

         if ( preg_match_all( "/$pattern/s", $post->post_content, $matches
 ) ) {
                 if ( $key = array_search( 'gallery', $matches[2] ) )
                         $atts = shortcode_parse_atts( $matches[3][ $key ]
 );
                 if ( isset( $atts['ids'] ) )
                         $attachment_ids = explode( ',', $atts['ids'] );
         }

         echo '<pre>'; print_r( $attachment_ids ); echo '</pre>';
 }
 add_action( 'wp', 'grab_attachment_ids_from_gallery' );
 }}}
