Persisting power settings through reboot

F8.x86_64 - Sony VAIO SZ640

I have been utilizing some power saving settings by writing certain values to /proc and /sys files. For example:

echo 1 > /sys/devices/system/cpu/sched_mc_power_savings
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs

However, upon rebooting my machine, these settings revert back to default values (0 and 500 in the above examples). Is there a way to force these settings to persist through a reboot or to create a script to run at system boot under root permissions?

Thanks for the help.
