Loaded module - speedstep_lib - needed or safe to unload

Hi,

Yesterday I tested 'cpufrequtil', but it looks as I don'T need it, so I uninstalled it.

It loaded some modules per 'modprobe'. I searched per 'lsmod' and already unloaded 'cpufreq_conservative' and 'cpufreq_ondemand'. CPU graphs still show up, everything seems to be working.

But there is one module left which I'm not sure of, 'speedstep_lib' which is loaded by the init script of 'cpufreq':

... # try cpufreq hardware depend modules for i in $(find /lib/modules/$(uname -r)/kernel/drivers/cpufreq \ ! -name speedstep-lib.ko ! -name p4-clockmod.ko ! -name "cpufreq_*" ! -name mperf.ko | sort -d -r); do ...

Is it safe to unload this module per 'modprobe -r ...'?

I want to avoid a complete reboot...

Thanks for all tips!

Best, Matthias
