You are wrong. I am able to save notes with maemopad, and do whatever i want in my own home directory. Ideally, you (as a normal user) have permission to write in your own home directory and that's where all the hildon-destop conf files are located in (~/.osso/*)

Anyway, i just tested fbdev, and surprisingly, it is not any slower than omapfb driver. Both get 6fps with fullscreened GLXGears. The biggestsurprise was, that with fbdev is actually possible to play youtube quality videos without big problems. With omapfb driver, video playback usually results a blue box or completely frozen device.

I was playing one song at the beginning until i remembered my camera doesn't have a microphone.
