Since I own one of those Centrino based Core 2 notebooks that create annoying buzzing noises when idle (= entering C3 or C4 power saving states), I'm looking for a program that creates artificial CPU usage. It should allow me to limit the CPU usage to a certain percentage (I know that there are a lot of easy ways to create 100% usage ;-).
Another option would be to disable the C3 or C4 states, but in newer kernels the sysfs interface to set the max_cstate on-the-fly was removed for some reason, and I don't always want to reboot after switching from AC to battery (and vice versa).
