If you are running KDE there is this as an interesting option that uses AcrossLite .puz files:

You can d/l the source and maybe complie the source using whatever Maemo SDK there is out there. I haven't done any development in years but it should be manageable if the libraries used are not system specific. Might need some interface tweaking but otherwise hard to imagine the basic application logic and code would not translate into Maemo.
