SUCCESS!

I have now got working gphoto2 on my n900. --capture-image works on full speed mode and i can list the abilities of the camera.

However --summary, --list-config and --list-files does not work at this point. There seems to a ptp protocol error.

I will continue playing if I have time over the weekend. When I get round to it I will upload the packages to extras-devel for people to use.
