(for Ubuntu ARM, file not found in Fedora ARM)
That should work as it is the most basic that can be done. Or, more
clearly execute this as root:
# echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
You can check which scaling-governors are available on your
kernel/system with this:
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governor
Cheers,

chkconfig --level 2345 cpuspeed off
(also file not found)
/usr/bin/cpufreq-selector -g performance
(from package gnome-applets, requires GNOME and I'm running in text mode only)
I also found this unanswered related message
http://lists.fedoraproject.org/pipermail/arm/2010-December/000791.html
So, how do I disable CPU frequency scaling in Fedora ARM from the console?
Thanks
