It seems to me that http://wiki.scummvm.org/index.php/Maemo should be the "official" wiki page. Someone could create a small page on wiki.maemo.org that points to the http://wiki.scummvm.org/index.php/Maemo page, to help people who search on wiki.maemo.org for ScummVM, but it probably shouldn't suplicate too much information, for ease of updating.
