[jQuery] How Would You Use Superfish Drop Down Menus with CSS Sprites2?

I have a menu that I've already set up with ALA's CSS Sprites2 (http://
www.alistapart.com/articles/sprites2/) now I have to add a drop down
menu into the mix. What would be the best way to achieve this, or
rather what would I need to change in the Superfish scripts to get
this to work?

This is what I have for the HTML so far...

<div id="header">
<ul class="nav current-about">
<li class="home"><a href="index.html">Home</a></li>
<li class="about"><a href="#">About</a>
<ul>
<li><a href="#">Contact Us</a></li>
</ul>
</li>
<li class="menu"><a href="#">Menu</a>
<ul>
<li><a href="#">Appetizers</a></li>
</ul>
</li>
<li class="private_dining"><a href="#">Private Dining</a>
<ul>
<li><a href="#">Private Dine Options</a>
<ul>
<li><a href="#">Option 1</li>
</ul>
</li>
<li><a href="#">Event Menu</a></li>
</ul>
</li>
<li class="events"><a href="#">Events</a>
<ul>
<li><a href="#">Events</li>
</ul>
</li>
<li class="merchandise"><a href="#">Merchandise</a>
<ul>
<li><a href="#">Merchandise</a></li>
</ul>
</li>
</ul>
</div>

Right now the hover effect works just fine, but the drop down menus
aren't visible—because of the -9000 text-indent on the css.
