You have to set it manually at bootup (add it to /etc/rc.local), but
after suspend/hibernate the values are normally restored by pm-utils
(eventually this might happen in the kernel). In the past some devices
needed a manual override in /etc/pm-utils-hd-apm-restore.conf But this
might not be needed anymore.
