If you want the module to be hidden or shown by default on page load you need to fire the function.
It would be something like this. Make sure you place each one below below the associated module html otherwise it will not work.
<script type="text/javascript">hideShow("ServerStatistics");</script>
<script type="text/javascript">hideShow("ShoutBox");</script>
That way, when the page is loaded, the modules should be at the state you want.
That should do it, and why you didn't remember this GE i don't know lol.
