They are all contained in the laptop-mode-tools Ubuntu package: you need
to activate each module changing some variables into the related .conf
file. Please, read carefully my other posts (in the ML) about the argument.

I don't use iwpriv to tweak the wireless power saving.
As already stated: the original laptop-mode-tools module use the value
in '/sys/class/net/$IF/device/power_level' but it save few power if
compared with 'iwconfig wlan0 power on' (I don't know why, but that what
I see). My self-made module use both the methods.
Again: write on the ML...
