what exactly was changed to make this work without the entire framework? I woud like to use the latest version of this file with your modification... thanks!

@mikepuerto - now that's a question!! I believe it was simply adding in the following at lines 9-12:

$.extend( $.support, {
    orientation: "orientation" in window,
    touch: "ontouchend" in document
});

There may have been other minor edits though, I'm not sure... :/
