rAXv2, hello!
To run int_ua's script(s) is simple enough - just connect to good network (or provide the stuff - image(s), they are listed inside the script,choose that which you want, kubuntu-mobile-n900-integration_0.1_all.deb, and install qemu-user-static ), choose the place on disk with enough free space, insert microSD card in cardreader and run as root.

But I dare to say that these distributions on n900, and at least in this form as now, are mostly "for fun" and no of much "direct" use with day-to-day applications (still VLC there works)
(there is no power management, the sensors do not work, graphics crashes, constant problems with booting, no phone functioning)
(It would be good to print some our logs/crash_reports here, for the developers to improve the distributions, but obviously it is not in this thread)
