How to allow HTML in Menu Title

Hello!

first of all thanks for the great work on the "burnt module"!

Everything is working fine for me but i need the functionality to allow HTML in the menu titles.
I already found this, but i think its not working for "burnt":

"Insert this in the template.php and HTML in the Menu Title Field should be allowed":

function phptemplate_menu_item_link($item, $link_item) {
return l($item['title'], $link_item['path'], !empty($item['description']) ? array('title' => $item['description']) : array(), isset($item['query']) ? $item['query'] : NULL, NULL, FALSE, TRUE);
}

Its not working for me.

What did i wrong or what do I have to change?

Thanks a lot!
