This is possible, but a slight modification is required:
1. alter the "skin/common_files/customer/main/register.tpl" template and replace this code:
Code:
{include file="customer/main/register_address_info.tpl"}
with this:
Code:
{include file="customer/main/register_address_info.tpl" need_address_info='Y'}
2. add corresponding smarty assign statement in "include/register.php" script.
PHP Code:
$smarty->assign('address_fields', $address_fields);
