Ok, I don't know. I have ubuntu-lowlatency 3.11 and I don't see any k-mod 
with lsmod that looks to me like it pertains to the cpugovernor. What 
governors do you have?

BTW, the governor and speed can be set without the CPUfreq utilities.

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
should show what is available
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
will show what governor is in use on cpu* (put a number from 0 to 3 in)
and writing to the same file will change it to whatever. Setting the speed 
is in the same directory scaling_speed maybe? There is also a file with 
the available speeds listed.
