--- Comment #1 from [e-mail] ---
Sorry, I hit enter on accident when filling out the title and it submitted the
form before I could describe the bug.  It's not a big deal, but I'd suggest
clarifying how to enable a governor in section 3.2.2.  Right now it's a bit
unclear how to enable a particular governer. All it says is enter the following
command:

echo [governor] > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

This is unclear to me because my first thought was to use "cpufreq_powersave"
(or whatever governor I wanted to use) in place of [governor].  However, this
didn't work and gave me the following error:

bash: echo: write error: Invalid argument

After googling I found the correct command to be the following:

echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

Maybe an example would help clarify how to do this correctly.

For reference, here's the page I was using:

Thanks for reporting this. I've updated Procedure 3.2 in commit    
d36218d91d98182861ddb5ebad0b37e8cca2f08b

As you suggested, I've given an example to illustrate what part of the full
governor name is required in the command.
