How about this

<ul>
{foreach from=$allsubcategories item=c}
{if $c.parentid eq "255"}
<li>$c.category</li>
{/if}
{/foreach}
</ul>

If you don't have $allsubcategories this is how to get them (I can't remember the thread)

add to /include/categories.php at the end before subcategories and cat assigns

function func_getallsubcat()
{
 $raj = func_get_categories_list("",true,"all");
 $raj1 = $raj['all_categories'];
 $ll = array();
 foreach ($raj1 as $k=>$val) {
  if($val['parentid']!="0") {
   $ll[$val['parentid']][]=$val;
  }
 }
return $ll;
}
$smarty->assign("allsubcategories",func_getallsubcat());
