Sorry, I wasn't clear - I was thinking that they should just be used for 
this case, rather than that more of them be added.

Most users will be logged into X, so it's the X keymap that's the most 
interesting one. X tools know how to remap the X keymap without 
requiring any sort of special privileges, so all we need is for the 
keycode to generate /something/. I think KEY_PROG* would make the most 
sense, and that's what we've adopted in Ubuntu.
