Can't you go to 600Mhz ?
I use a daemon with a lazy-to-raise policy, that is really efficient for 
powersaving and quiet comfortable.

HDD on -> + 2W
FAN on -> +1W
DynamicClock off -> + 2W
Wifi powermanagement off -> + 2W
USB-mouse -> +2W

When idle (I even dont touch the keyboard), using ubuntu hoary & gnome, 
my laptop stabilize to 10,5W in laptop mode (hdd in standby).
For a 6-cell battery of 42Wh (like mine) It can run exactly 4 hours.
When in use, average consumption is 12W.
