I was searching for a tutorial on how to install Ubuntu/Debian on n900 and be able to boot it using uboot and found this https://wiki.ubuntu.com/ARM/n900.

What's interesting about it, is that it uses the kernel modules and kernel from MeeGo. (2.6.37... instead of 2.6.28.. from maemo)

I tried to install it following this manual, but gave up in the middle.
Probably going to attempt again in the future.

What I don't understand, is why can't someone just release the whole flashcard image to torrents and then link it somewhere.(wiki, forums, etc) Is it because the final "product" has proprietary parts?
