You could start by running powertop from http://www.linuxpowertop.org which 
would also tell you the processes that keep your CPU from going into 
powersave-states. Otherwise, just pull the stats 
from /proc/acpi/battery/BAT0/state while running on battery. I got my X60s 
down to 7.5 to 8 W/h working under KDE/Openoffice.org with a dynticks kernel 
(2.6.21 vanilla / debian etch) and some patches from the website of powertop.
