And of my linux knowledge: I have used and installed the last ten years different linux distros for very old low end computers as well as for some newer. Main problems have been with too little ram, resolution, wifi, 3D acceleration and printers. For these I have found answers with google search or from youtube. I have never needed to know more but with N900 it is different. The systems lacks as a default many commands, it is armel, there is cssu with default apps but then testing which only has some that work or you only find from devel repos. Repos have been hard to find. Then on the forum when people talk they mention needed packages to get things done which are found only from development repo. And then suddenly I can't install packages needed cause they conflict with my distribution which I have put together as guided from a scratch. So in here there are many challenges for me.
