.. and so it happens I decided to rewrite the guide (not done yet), setup repository for N900 (done, though my dropbox got suspended for awhile), do some packaging (kernel, firmwares, dsp binaries and configs packaged, more coming) and finally try to write a small daemon to handle charging, leds and backlight. I have also compiled a special 2.6.37.6 kernel for arch users, which include all (150+) patches from Meego/Mer, partial CK-patchset including BFS scheduler and BFQ i/o scheduler. Yes, very nice, you're welcome. I'll keep you posted.
