I believe the answer to your question is YES if you have the aluminum powerbook and it should look better than the ibook. The iBook keys are translucent with screen printed letters. The Powerbook keys are opaque plastic with laser cut translucent letters. If you were to add fiber optic lighting by following the iBook mod then you would have a backlit keyboard where only the letters show [just like stock]. Also i believe in the top right corner of the casing, there should be a small area of space to hold our fiber optic light source. I'll update this post later with a link to a disassembly of the alum pb.
