Modules API version 2

I have a quick question. Can I use the modules API version 2 in FreePBX 2.5.x?

I was following the hello world example on the wiki page (http://www.freepbx.org/trac/wiki/ApiModules2) but get a 404 not found error when I click on the menu entry of my module.

It seems FreePBX is only looking for page.modulename.php and not for admin.modulename.php.
