this post is just for the 'record' before I forget, and this is as good a place as any. One never knows when such a swap may be useful.
I swapped a dual USB iBook keyboard onto my 667 DVI PowerBook G4 Titanium tibook. While connector cable length/shape is obviously different, the connector is the same. Plugged iBook keyboard in while asleep, awoke to find iBook keyboard functionally identical to original TiBook keyboard.
that is all,
