Hi,
I tested the EEEPC FSB downlocking that was recently integrated into tuned
(laptop-battery-powersave profile), the results follows:
Runlevel 5
default : Pavgidle = 11.3 W; throughput: 5597 ssj_ops, Pavgload = 18.7 W
downclocked: Pavgidle = 9.6 W; throughput: 4330 ssj_ops, Pavgload = 14.8 W
Runlevel 1
default : Pavgidle = 9.5 W
downclocked: Pavgidle = 8.3 W
The system throughput drops when downclocked, but the powersavings are great. I was
testing on Fedora 14 and Asus 1000H
This feature was integrated into laptop-battery-powersave profile of tuned-0.2.19-1.
Currently it is in testing:

Feel free to test it and if it works for you do not forget to give it some positive karma
;)
regards
