Making a custom *.bin is not what the N900 is about (for me)! I'm not a follower, I don't want the same setup as anyone else. I don't want the same "tweaked" system as someone else, I want a stock OS and I tweak and hack the hell out of it until it's correct. I change the setup every reflash (1 - 3 months). Or you could just create yourself a little script and auto install all the files and tweaks you need and modify files you need. It may take some time, but will work... All in one script
