You are running by default, the Intel Pstate system in Ubuntu 14.10. To use the older ACPI method, you need to edit the grub file and reboot:
Open a terminal alt+ctrl+t and enter the folowing lines:
sudo cp /etc/default/grub /etc/default/grub.backup
sudo nano /etc/default/grub
In the Nano editor, look for the line beginning with GRUB_CMDLINE_LINUX_DEFAULT
At the end of the line add intel_pstate=disable
The whole line shoud now look like this
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=disable"
press the keys ctrl+o to write the file, and ctrl+x to exit Nano. Then in the terminal, enter the following command to update Grub
sudo update-grub
You should now reboot your computer, and find that you are able to set the governors as you did in 14.04
