I agree with Sven that the toolkit is not responsible for telling
the input driver about an updated kernel keymap.

The way of selecting a keymap is very specific to the underlying
system, but how far is it supported via GDK at all? How does Gnome
change the keymap? Are all GTK+ instances notified about a switch to
flush certain states or cached information?
