"If you want CPU frequency scaling to work (which you almost certainly do, whether you know it or not), you still need to add acpi_osi=”!Windows 2006” to the kernel boot line in /boot/grub/menu.lst, and add acpi-cpufreq to the contents of /etc/modeprobe.preload. That's all - you don't have to preload anything else, and you don't have to set the governor, that all works ok once you have made these two changes."
