If you follow these exact instructions, (directly after flashing), this will get maemo-mapper completely working on the n800, you can even upgrade to the latest version of maemo-mapper after that.

Since the release of 1.3.3 and 1.3.4, these instructions will still work, I am just not sure that they are needed. I have lots of 2006 apps running on my n800 and I have not tried to install maemo mapper from scratch since the creation of 1.3.3 or 1.3.4

This was strictly posted as a howto install from a fresh flash, and get the above mentioned items working. If you can not get it to work any other way, than this should work, but again, I do not think it is needed. Good Luck!!
