¿Cómo hago para que "modprobe acpi-cpufreq" cargue al inicio?

He estado intentando poner los procesadores de mi Intel core 2 con en Ondemand, leyendo varios hilos de Blogdrake lo he conseguido, pero al reiniciar, me toca volver a repetir el proceso. ¿Cómo podría hacer para que se cargara al inicio?

Esto es lo que me suelta konsole nada más arrancar:

[root@localhost ~]# cpufreq-set -c 0 -g ondemand
Error setting new values. Common errors:
- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
   for example because of hardware which cannot be set to a specific frequency
   or because the userspace governor isn't loaded?
[root@localhost ~]# cpufreq-set -c 1 -g ondemand

[root@localhost ~]#

[root@localhost ~]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor: No existe el fichero o el directorio
[root@localhost ~]# cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
cat: /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor: No existe el fichero o el directorio
[root@localhost ~]#

pero si antes pongo:

[root@localhost ~]# modprobe acpi-cpufreq

Los comandos anteriores ya funcionan y podemos ver se supone que ya está en Ondemand:

[root@localhost ~]# cpufreq-set -c 0 -g ondemand
[root@localhost ~]# cpufreq-set -c 1 -g ondemand
[root@localhost ~]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
ondemand
[root@localhost ~]# cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
ondemand
[root@localhost ~]#

[root@localhost ~]# cpufreq-set
At least one parameter out of -f/--freq, -d/--min, -u/--max, and
-g/--governor must be passed
[root@localhost ~]# cpufreq-info

¿Cómo hago para que "modprobe acpi-cpufreq" se cargue en el arranque?, ¿Hay alguna aplicación gráfica con la que se pueda cambiar rápidamente de gobernador como se hace por ejemplo en un Android rooteado?

Gracias.
