It does that by checking for existance of files in sysfs doesn't it?
If so, nuking the cpuspeed service will break that, as the modules won't
get loaded, and the sysfs files won't exist.

Read the initscript. In some cases it doesn't start the daemon but
sets up the kernel ondemand module.  (You don't want ondemand on all
scaling implementations due to latency reasons).
