you can't move the goal posts mid game, not fair ;)

Presuming your links actually are something like (notice the first link)

<div id="navigation">
<ul>
<li><a href="#">A long link that goes onto another line</a></li>
<li><a href="#">Item 1</a></li>
<li><a href="#">Item 2</a></li>
<li class="current_page_item"><a href="#">Item 3</a></li>
</ul>
</div>

and not what you posted above

then add

padding: 0 0 100px 0;
margin: 0 0 -100px 0;

to

#navigation ul li{}

It then seems (make sure you check) to work in Firefox 2+ Opera 9.5 Safari3.1 IE6+ & Konqueror 3.5+
