Avoid high kernel_task utilization on 2005 PowerBooks
I was able to confirm the original poster's problem, even after installing the 2005-007 security update. Wetzel's suggestion brings the kernel_task CPU use down to about 0.3% instantly: sudo kextunload /System/Library/Extensions/AppleUSBTopCase.kext/Contents/PlugIns/AppleUSBTrackpad.kext/ To get your trackpad back, just run this command (your kernel_task CPU use will go back to about 10% instantly): sudo kextload /System/Library/Extensions/AppleUSBTopCase.kext/Contents/PlugIns/AppleUSBTrackpad.kext/ I've submitted a bug with Apple, the ref # is: 4222723.

I submitted this bug to apple and they have given it the status "closed". Does any of you know whether the bug has been resolved?

Save your work before you try the above hint, because
just caused my machine to give a kernel panic. I've tried it again after a reboot, and this time, it succeeded in unloading the extension, and kernel_task CPU usage has gone down correspondingly.
