f2thak, is the problem you are having with programming the PS3 controller with the N900 Bluetooth mac address?

any easy solution maybe to download whats called a linux 'Live CD'

basically a live cd is a full linux setup that runs of the cd/dvd - so you dont have to mess up your windows stuff (i run windows like you)

with the live cd if its able to get to the internet you can download the sixpair that Smoku compiled and connect the PS3 controller to the pc and program the Mac Address of your n900 to the controller.

If you are wanting to do this, I am sure a lot of people here will try to help.
