If you want a dummy link in main menu to display a certain page and/or with configurable blocks visible on this page, then you would need a dummy module for it to be possible to set blocks visible on this link's page without them being visible on all pages.
You would just need a short xoops_version.php with a little content to say that it has a main menu entry, but no admin and that it should point to the page, you want displayed by following this link.
If you are stomped by this, I'll write some more thorough code in a few hours, when I have time for it.
