After lots’s of tries and help from different people I got my own kernel running on the N900, which is based on the Debian kernel package. So far it just offers basic features (e.g. framebuffer, keyboard) and is missing some important ones (e.g. touchscreen).

First of all the Debian on N900 page moved to https://elektranox.org/n900. Now about the recent changes:
As I promised in my last post I improved Debian support. The changes since initial Debian support are:
In short: All kernel related stuff is solved. Remaining issues are
