Technically, the option is enabled as default just because of the
configure script.  In the kernel configuration, you can choose freely
as you like.  (And this feature will save lots of battery time.)

But, the default power_save value is 0 in the recent version, so
passing power_save=0 shouldn't give any difference unless you set
other values in somewhere else.
