Yes, the default settings are sane. Disabling it by default is necessary
because of unexplained system hangs on some laptops. The only thing that
should change in that area is that the default HD powermgmt settings in
the laptop-mode.conf should be changed to 254 instead of 255, but
that'll happen automatically the next time they sync up with Debian. And
any power management setting <254 should be set only when laptop mode is
enabled -- but even that is not usually necessary since laptop mode
tools sets the spindown timeout (hdparm -S) instead.
