Canonical place to configure power management


I use powertop to enable power management for various devices on my laptop.
I wonder where I can store these configuration options permanently. I looked
into pm-utils and guess I can use this package but there seems to be no
documentation how one should use pm-utils.

Some examples of the options in question like displayed in powertop:

>> Bad           Wireless Power Saving for interface wlan0
   Bad           Enable SATA link power management for /dev/sda
   Bad           NMI watchdog should be turned off
   Bad           VM writeback timeout
   Bad           Enable Audio codec power management
   Bad           Autosuspend for USB device BCM2045B (Broadcom Corp)

How do you enable these settings? Do you store them permanently?
