Since you included reaver and walsh in cleven. walsh is fixed now I compiled it and it works(see reaver thread for compiled binary): http://code.google.com/p/reaver-wps/.../detail?id=100

anyway, I would wait a bit before porting all this to maemo. Reaver will probably be included in the aircrack-ng suite, so if it's ready we only need to update aircrack-ng in the repos
