Supposedly, if you have the permissions set correctly on the WordPress files (no, I can't figure it out either, although it did happen once by magic when I used an automated installer), the autoupdater doesn't even need this.
If you have access to your wp-config.php file, you can enable the autoupdater without FTP by adding this line:
define('FS_METHOD','direct');
WordPress will now update directly without requiring FTP access.
