I've tested those directions on a new Thinkpad (T430s) after finding 
them posted in many places and found no measurable power use difference.

Using powertop, however, does produce significant improvements.

The most important thing to know about powertop is that it does not make 
permanent changes.  If you get good improvements from powertop, save the 
HTML report from the program.  The HTML report will have a table 
containing commands that enact the changes that powertop suggests.  You 
can Ctrl+click and drag to select those cells (at least in Firefox) and 
paste them into a shell script that you can run on boot.
