Avoid high kernel_task utilization on 2005 PowerBooks

Save your work before you try the above hint, because
sudo kextload /System/Library/Extensions/AppleUSBTopCase.kext/Contents/PlugIns/AppleUSBTrackpad.kext/
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.
