I am typing this on a 1.33 iBook, but due to a loose joint with the Airport card which caused a KP on startup I have had to disable it and use a USB Ralink wifi adapter.
I also had to shim this iBook because unless you pressed hard on the left side next to the trackpad the machine started up with no video (black screen). Probably related to the bad solder around the Airport card.
Consequently it might run a little hot and so I'm using G4FanControl http://www.andreafabrizi.it/?g4fancontrol to make the fans come on early.
I'm sure yours will be fine, but this is just a heads up ...
Cheers
Hugh
