Not 100% certain, since I haven't dissected it yet, but here's what I can tell you. There is a link in the auth.tpl that says

If you have disabled Javascript in your browser click here

It changes to

If you have enabled Javascript in your browser click here

once you actually click on the link and vice versa.

The code is something like this

{if $js_enabled}
{$lng.txt_javascript_disabled}
{else}
{$lng.txt_javascript_enabled}
{/if}

Other than this all I can offer up is what the change log says

Fri Jan 3 16:50:00 MSK 2003 [+] - svowl - This feature allows customers with disabled JavaScript in browsers to make purchases with the X-Cart.

Doesn't help much, I know, but it's the best I can offer up right now.
