I managed, after getting Pentaquark (the Nokia N800) back into a usable condition, to get kbdd installed and working, and it's /okay/, but not great. Graviton (the HP iPaq), after installing the drivers that FROM WITH THE KEYBOARD, doesn't connect. I can pair it, thru the bluetooth manager, but that's it.
And, when it IS talking to the nokia, the period/> key doesn't seem to work. everything else does, tho. So, I think just that key is busted.
