Code

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

  // Back up the existing theme functions.
  $themes = variable_get('dhtml_menu_theme', array());
  unset($themes[$theme]);
  foreach (array(
    'menu_item',
    'menu_item_link',
  ) as $hook) {
    $intercept = 'function';
    if ($theme_registry[$hook]['function'] == 'devel_themer_catch_function') {
      $intercept = 'devel_function_intercept';
    }
    $themes[$theme][$hook] = $theme_registry[$hook][$intercept];

    // Replace them with our own. These will "preprocess" and call the real functions.
    $theme_registry[$hook][$intercept] = 'dhtml_menu_theme_' . $hook;
  }
  variable_set('dhtml_menu_theme', $themes);
}
