I've succesfully installed Kubuntu 11.10 with the given script. Even the wifi is working out of the box (without commadlining). The plasma desktop works perfectly. The big problem is the sound is not working for me.

I managed to switch on the swap, that swap which is a file located on the kubuntu's root folder SWAP.swap (512 mb) I have to activate it after each start via terminal.

I installed some packages:
Moun
Firefox
Chromium youtube-html5 almost works problem is the sound (I think)
Vlc
some kind of picture viewer

Multitasking works great with swap activated. (firefox, openoffice, system manager)

Thanks for your work.
Finally I can use my N900 as a real computer.
