I'm going to be spending the next week at a conference, and I know
I won't always be able to be near an outlet.  A co-worker running
one of those other OSs (his is from Redmond) with the same laptop
can get nearly double the time out of his two batteries that I can.

What tips do people have for making your battery last as long as
possible, when you want to use the computer?

I have an atheros wireless card, which I guess I can't do powersave
with.  I have radeontools installed for shutting off the backlight,
I have estd set up to adjust the CPU frequency down when I'm not on
AC. I mount / (my only partition) with noatime, nodevmtime, and soft
dependencies.

I've got a Latitude D600. I'm running a few days old current.
