Tu n'as pas choisi le plus facile
L'algorithme n'est pas optimisé, mais ça tourne.

Le code est valide sous IE5.5 -> IE7 mais je n'ai pas pu tester sur IE8 (faudra peut-être modifier les commentaires conditionnels <!--[if IE 7]>)

Code :

{if $count > 0}
<div id="nav">
{assign var="parentActif" value=0}
{foreach from=$nodelist item=node}
{if $node->index == 0}{assign var="prevnode" value=$node}{/if}
{assign var='current' value='<ul class="sub">'}
{if $node->current or $node->parent}{assign var="parentActif" value=$node->hierarchy|truncate:2:""}{/if}
{if $node->depth > $node->prevdepth}
     {if $prevnode->parent or $prevnode->current}{assign var="current" value='</li></ul><ul class="sub_active">'}
     {/if}
{$current}
{elseif $node->depth < $node->prevdepth and $prevnode->hierarchy|truncate:2:"" != $parentActif}
{repeat string='</li></ul><!--[if lte IE 6]></td></tr></table></a><![endif]--></li>' times=$node->prevdepth-$node->depth}
{elseif $node->depth < $node->prevdepth and $node->hierarchy|truncate:2:"" == $parentActif}
{repeat string='</li></ul>' times=$node->prevdepth-$node->depth}
{elseif $node->index > 0  and ($node->current == false and !$node->parent)}
</li>
{elseif $node->index > 1 }</li>
{/if}
{if $node->depth == 1 and ($node->current or $node->parent) and $node->index > 0}
</ul><ul class="current">
