in the instructions for the KB, it says:
"In the bluetooth programme, use the option to add a new device and follow the instructions on the screen. If you are prompted for a passkey, let the program create it."

- so, I thought it had more to do with the N900 than the KB. 0000 and 1234 didn't work, unfortunately.

I'll have a look at doing it manually with the terminal commands... brb

Edit:
Does it matter if I'm running power-kernel v0.46?
