1. In Content Types, create a new content-type called "frontpage."
2. Rename page.tpl.php as "page-default.tpl.php".
3. Create a new page.tpl.php and put this code in it:
   
   <?php

if ($node->type == 'frontpage') {
include 'page-frontpage.tpl.php';
return; }

include 'page-default.tpl.php';
return;

?>
4. Create a new template file for your front page called "page-frontpage.tpl.php." The easiest way is to copy the page-default.tpl.php, then edit it to make your changes.
5. Upload all three files to your asuzen theme.
6. In Create Content, create a new frontpage page.

That should do it!
