I checked on the Linux Bug Tracker (or something related) and it says a patch is out.
Run "sudo apt-get update && sudo apt-get upgrade" and if that doesn't work,
install indicator-cpufreq: "sudo apt-get install indicator-cpufreq", log out, and login.
Look at your menu bar. A pic of a CPU will be there, and click. Select Powersave from the menu.
