I tried following this guide: http://nokia-n900.com/how-to-adding-...powerkey-menu/ with no success. I figured I need to replace typographical quatation marks with " and I am able to reboot from command line with /usr/bin/sudo reboot (without sudo gainroot) and I have reboot item in the power menu, but it does nothing when pressed. Any ideas? Is that guide wrong?

UPDATE: I found a way to to this. It was rather easy in the end.
