The deskutils/tpb port provides some functionality.

You could try running xev to find the keycode of Fn, and then xmodmap to
map it as a modifier key. My experience (on a TP R52) is that Fn has a
keycode, but that it cannot be usefully combined with other keys. I
would be happy to discover otherwise for reasons similar to yours.
