I can't find you now but I remember one or two forum members doing CPU swaps.
I have a g4 7447a free for the taking. I just swapped-in a 1.5GHz powerbook 12" logic board with a a g4 7447b into a 1.33GHz powerbook with a 7447a. The 7447a had a bad ram slot but beautiful case and screen hence the swap.
If you are interested, reply below or better yet, send me a PM so I can send it to you.
