what does : locate cpufreq.ko say ? 

It should tell:

,----[ locate cpufreq.ko ]
| /boot/kernel/cpufreq.ko
| /boot/kernel.old/cpufreq.ko
| /usr/obj/usr/src/sys/MONNOYAU/modules/usr/src/sys/modules/cpufreq/cpufreq.ko
`----

Then, all you have to do is to put a line along your
/boot/loader.conf:

,----[ loader.conf ]
| splash_bmp_load="YES"
| vesa_load="YES"
| bitmap_load="YES"
| bitmap_name="/boot/splash.bmp"
| acpi_load="YES"
| cpufreq_load="YES"
`----

and tweak your power_profile* in /etc/rc.conf

Hope that will help.

Cheers,
