There is no sensor in the n8x0 to detect rotation, must be done manually. You can either open ASUI and press the A buttons or if you have Telescope you can bind the zoom keys to do rotation. You will need at least one window open, press Home to see Telescope's window thumbnails and then the zoom keys will rotate left or right. Telescope doesn't execute key actions in its launcher. http://asui.garage.maemo.org/about.html scroll to the sixth paragraph for instructions.
