Drupal 6.x pathauto and token module problem

Problem Description:

If you try to use patterns like [menu], [menu-raw], [menupath], [menupath-raw] for nodes, the module (pathauto) does not support the feature.
Expected result was to generate menu paths including the inheritance. But unfortunately it doesn't.

Analysis:

The reason might be in token\token_node.inc , where it uses the drupal 5.x old stategy to retrieve the menu using
Global $_menu. But unfortunately (or fortunately!) drupal implements a totally new menu system for version 6.x

Solution:

Have not solved the problem yet. but one solution might be using menu_get_menus() method to retrieve the menu information adopted from the menu module and then rebuilding the array containing the items menu, menu-raw etc.

parent url aliasing information may be kept in knowledge while producing the items.
