Actually it's rather easy, since i've just done it
Open up forumdisplay.php and find:

PHP Code:

    if ($thread[sticky] == 1) {
         $thread[typeprefix]=$stickythreadprefix.$thread[typeprefix];
      } 


Underneath add;

PHP Code:

    if(!$addedRow and $stickyids and $thread[sticky] == 0 and $addedRow = true){
    eval("\$sepsai = \"".gettemplate('forumdisplay_sepsai')."\";");
    } else {
    $sepsai = '';
    } 


Then open up forumdisplaybit template, and at the top add

$sepsai

Add a new template forumdisplay_sepsai ;

<tr valign="top">
 <td colspan="10"><img src="{imagesfolder}/clear.gif" alt="" width="1" height="1" /></td>
</tr>

This makes all announcments & stickies above the line. If you used my other way without hacking, you'll have to uninstall it.
