What about just creating a simple new function that checks if the 
Category Parent field from the database/$post is anything other than 0. 
So you'd be able to go

// Inside the loop
<?php    if (!$subcategory($post)) {
             // Whatever you here
}?>

That way you wouldn't have to change anything and could easily do it as 
a plugin or even a hack.
