Joerg, I think your module does something, but you are not using it properly. With a value of 254, it has no effect. Using your module, you will only see a difference using odd values, because the least significant bit is what enables the ICTC. Try some small odd values like 3 or 7 and see what happens. The information on ICTC usage is from "MPC7450 RISC Microprocessor Family User's Manual", section 10.3. I have put my code online, you can download it from <http://www.toojays.net/portal/Members/toojays/ict-0.1.tar.bz2/download>. I also started a Wiki page about power consumption on the iBook G4, but currently it has no really new information. cheers, John
