Actually, cpufrequtils do manage the CPU speed (or to be exact, it
tell the kernel to do it).  If you edit /etc/default/cpufrequtils, and
set ENABLE="true", it will turn on ondemand cpu frequency scaling if
the required kernel modules are loaded.

How is this handled in Ubuntu?

I've had ideas to implement support for CPU detection into discover
v2, but it isn't written yet.  It would allow us to detect it and load
the correct kernel module.

Perhaps.  We will only know when someone succeeded if it was easy to
make or not. :)
