No, I assumed the application enabled it by itself. I was actually going to edit my post and this bit of info, but you mentioned it before I did. :) Once I tried it, the application worked like a charm, albeit with one problem:

I couldn't get diacritics, upon which my language (portuguese) depends heavily upon, to work. Changing the language to Brazil wouldn't help. I didn't try Portugal, but I'm not sure it would work.

This is a known bug in maemo since Diablo, I think, though there's a workaround described in http://labs.danilocesar.com/blog/200...cents-on-n800/ , which I couldn't get to work on extkbd. It works on Fremantle, though, I was using it before trying extkbd.
