This cryptic line means your (probably cheap) keyboard does not support HID bluetooth profile so you are out of luck with easy nice out of box experience on any system including N770 and N800. You need extra drivers - kbdd in case of n770 or n800. See http://fanoush.wz.cz/maemo/#kbdd If your keyboard is not one of those already supported you need to modify kbdd to add support for your keyboard (basically means to figure out keycodes the keyboard sends when keys are pressed and released).
