I'd like to install cpufreq modules on my server . I tried
sudo modprobe acpi-cpufreq
but got the error
FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.18-238.12.1.el5xen/kernel/arch/x86_64/kernel/cpufreq/acpi-cpufreq.ko): No such device

And uname -r gives 2.6.18-238.12.1.el5xen
ls /lib/modules/2.6.18-238.12.1.el5xen/kernel/arch/x86_64/kernel/cpufreq/
gives
acpi-cpufreq.ko mperf.ko powernow-k8.ko speedstep-centrino.ko
Do I have everything required to install cpufreq ? Is my system compatible to have cpufreq ? If yes, what steps sshould I follow to install cpufreq ?
When I entered BIOS settings, I was not able to view option to change CPU performance settings either.
Kindly tell me what to do.
