Its great to get into overclocking. I love it! But with that said, laptops are touchy. You need to watch the temps very carefully. I have been using an iBook as of late and notice that after an hour or so it gets uncomfortable on my lap. They get hot and overclocking my just cause some issues with both electro migration and lower life of the cpu. You will be surprised at how much the ram will help you out. -maestro

Well, I have not seen any mods in that processor range for iBooks so I would say no.
It looks like the overclocking instructions should be similar to modding an older iBook or a Mac mini for that matter. You can see if these instructions can act as a base for your new project. Would love to see a mod guide on it.

Yes, actually someone has. The 500 and 600mhz G3 iBooks were easily modified thanks to very, very simply re-soldering of wires.
After that all other G3's and G4 iBooks were very complex to overclock and really no one tried it. That was until the 1.2 and 1.3GHz iBook G4's came out. They use the same chip as the 1GHz eMac. If any of you know the 1GHz eMac chip (Short lived and now only used in iBooks) had sixteen "relay switches" around it's perimeter. By moving the switches into different positions the CPU becomes faster, or slower. If I recall correctly the top speed anyone got out of a 1.33GHz iBook was 1.75GHz and it heated up very bad.
I also recall a Japanese site modding a 14'' iBook G4 to 1.70GHz and adding a very large amount of thermal gel to the CPU and piggybacking off the battery connector a small fan that was burried beneath the thermal gel that was hooked to a cheap big mouth straw that sucked air onto the CPU from the Airport Compartment.
