I've built a new package with all the problems fixed. It starts neatly from an icon, and I've updated the GNU Emacs on Nokia N900 install guide:

Haven't yet uploaded the new package, as I'm having connection issues, will upload in a couple of hours.

I've updated the guides, on how to remap the keys, how to edit the necessary .emacs file directly in GNU Emacs etc. but can't upload the guides temporarily.
