You don't need to unzip anything. Open Konsole, copy/paste:
kdesu dolphin /etc/modprobe.preload
and add the line powenow-k8
Save! Reboot.

Why bring
dolphin into the act? All it does is open
kwrite anyway, and leave two windows to close. The command;
[<user>@localhost ~]$ kdesu kwrite /etc/modprobe.preload <Enter>
calls kwrite with
root permissions directly, and opens
/etc/modprobe.preload ready for editing, when the
root password is given.
Dolphin is totally
unnecessary for this purpose, and just one
extra window to close after the file is
edited and
saved.
