huh?

gtk filter functions work smoothly with XKB events in 2.0 and 2.1.
That is what we use in the gnome-settings-daemon.  You do need to do
a touch of X magic to find the event id for the extension, but the
amount of code is pretty trivial and easily compartmentalized.  The
only other ugliness is the 2 fold checking that
    - you can compile the Xkb code
    - the user's server supports it.  Note that the majority of Sun
      users have massively broken XKB implementations, so this is
      not a corner case to be ignored.
