Code

function dhtml_menu_theme_registry_alter(&$theme_registry) {
  global $theme;

  // Back up the existing theme functions.
  $themes = variable_get('dhtml_menu_theme', array());
  $themes[$theme] = array(
    'menu_item' => $theme_registry['menu_item']['function'],
    'menu_item_link' => $theme_registry['menu_item_link']['function'],
