Hmm, I get the BadKey also, and I did not realize that until now. My approach
to this type of problem is to use xev to see what keycodes each key is
sending, then use xmodmap to map keycodes to keysyms, then more xmodmap
commands to clear the modifier keys and then set them to what I want them to
be. I think you want to map the win key keycode to Meta_L, then clear mod1
and then add Meta_L to mod1.
