Hello,

I own a T42 and can go slightly under 13W (actualy under 10W in emacs 
without X, 10.5W with X doing nothing)
AFAIR, here is the list :

- Undervolting CPU to very-low limit (no pb so far)
- DynCLock / RovClock on the GPU
- sync HDD less often, use agressive caching, noatime
- throtle wireless, see man iwconfig  /power
- push back fan start point
... and maybe a few other things I miss, I did that almost a year ago.

But the 2 first points are fundamental, as they do not alter comfort, 
while reducing *a lot* power consumption, therefore heat generation, 
which is unpleasant.

Regards
