xkbd and matchbox-keyboard both use XTest which is limited into
synthetizing X key events.
Hildon keyboard communicates (through X messages sending UTF-8 strings
I think) with the application text widget GTK IM context object(s).
It doesn't use XIM.
If you want to use XIM input method on Maemo, you could try
adding the standard Gtk im-xim entry to /etc/gtk-2.0/gtk.immodules
(and maybe removing the hildon-im-module entry) and the corresponding
standard Gtk im-xim IM module library to /usr/lib/gtk-2.0/2.*/immodules/
directory. And then of course porting & running some XIM input method
daemon on the device.
