Maemon korvaaminen kokonaan Ubuntulla: N900

[samsunix]

Tarvisin apuja arm-ubuntun asennuksessa  N900:lle. Tarkoitus on siis asentaa käyttöjärjestelmä laitteen sisäiselle muistille - ei microSD-kortille.

Löysin jonkinlaista ohjeen tynkää täältä:
http://www.smartphonetab.net/forum/showthread.php?3268-Ubuntu-Natty/page8
"käännös" edeliselle:
http://talk.maemo.org/showthread.php?t=74084

Tiedostoja löytyy täältä:
http://cdimage.ubuntu.com/releases/12.04.2/release/

ubuntu ja n900 halailua:
