Hi Andreas. I haven't seen any, but it can't be that hard to make.. ;)

Something like this:

Create a file in your fileadmin folder, and name it "menuFunc.inc"
Then fill it with this content:

-- cut --
<?php

class user_menuFunc {

 function hideHiddenSubs($menuArr ,$conf) {
  $new_menuArr = array();
  while (list($k,$v) = each($menuArr)) {
   if (!$this->gethidden($v['uid'])) {
    $new_menuArr[] = $v;
   }
  }
  return $new_menuArr;
 }

 function gethidden($uid) {
  $hiddenFlag = 0;
  while ($uid!=0) {
   $res = $GLOBALS['TYPO3_DB']->exec_SELECTquery('*','pages','uid='.$uid);
   $row = $GLOBALS['TYPO3_DB']->sql_fetch_assoc($res);
   $uid = $row['uid'];
   $hiddenFlag += $row['hidden'];
  }
  return ($hiddenFlag>0);
 }
}

?>
-- cut --

Then in your SETUP field, insert this line:

-- cut --
page.includeLibs.menustuff = fileadmin/menuFunc.inc
-- cut --

And in your TMENU object, insert this before the NO part:

-- cut --
itemArrayProcFunc = user_menuFunc->hideHiddenSubs
-- cut --

This will check if the current menuitem or it's parent or (parents parent 
etc.) pages is hidden, and exclude that from the menu.
Only problem is that if you set "maxItems =5" then $menuArr only contains 5 
pages, and if 1 of these is behind a hidden page, only 4 pages will be 
shown.
