In the meantime, I'll study more about the iBook G4's motherboard and how to modify it to fit a G5 processor.
You have my full support in this. Here are some things I think you might want to consider during your attempts :
1) The tachyon inverter on the G4 has an amplitude which is 0.0045 terramotes out of phase with the G5. You will have to somehow compensate for this - maybe a Garn-Heinen bridge if you have the parts?
2) As any fule kno, the quantum spin of the iBook's case is DIRECTLY PERPENDICULAR to the Boseine capacity of the G5's heatsink.
3) If push comes to shove, try reversing the polarity of the flux capacitor.
Ignore all the haters on here. They are just jealous morons who do not recognise technical genius when they see it.
Good luck and I hope you remember me when you are famous and having sexual relations with such babes as recently-separated Reese Witherspoon, the star of such classics as "Cruel Intentions" and producer of the upcoming magical fantasy, "Penelope".
