In the Ajax mode, as long as you include a link to the external file itself within the menu's DIV, search engines will be able to use that to crawl its contents. For example:
Code:
<div id="smoothcontainer">
<noscript>
<a href="link to site map for search engines and user with JS disabled">Site map</a>
</noscript>
</div>
You might even want to change the NOSCRIPT tag to just DIV if you're concerned search engines do not crawl the NOSCRIPT tag, though as far as I understand it, all the major ones do.
