1) Which Filesystem to use ?
I disagree here. I would use ext3, because of the journal. A laptop is very rarely used in such stable environment as a desktop, and I would choose a the additional fs-security over few minutes more runtime anytime. But of course I understand your point.
ext3 can also be set to commit the journal less frequently, (30 mins instead of 5 mins). To be honest though, unless you want the hard drive to sit in power saving mode all the time, the small write required to write a journal every 5 minutes will use almost no power.
2) Which Window manager to use ?
I use Openbox (on my Pentium 75 Notebook with 14MB ram), but any *Box or Windowmaker, even enlightenment should do. Here http://www.windowmaker.org/features-performance.html is a nice comparison between some Windowmanagers.
They miss out Fluxbox (and Openbox), which both beat most others on that list, IMHO ;)
ACPI unless it lacks features you need.3) APM or ACPI ?
4) Which kernel to use ?
I am a bit lost here, I use the gs-sources because of the cpu speed scaling options, but I do not know if this is the best choice.
I use gentoo-sources, but don't ask me why. I couldn't give a solid reason.
gentoo-sources are going to give you better desktop performance than vanilla, there is little reason to not use them, (unless they break on your hardware). gs-sources pack even more features in, but in my experience are less solid than gentoo-sources.
5) Framebuffer or not ?
Is framebuffer power consuming ?
I would choose framebuffer over X anytime, because its a lot less
CPU/Memory consuming. I was told that Links and Mplayer run in FB
without problems.
But again, framebuffer is more CPU consuming than VGA text mode. So if you want ultimate power saving, choose text mode, but set it to a high number of rows/cols (kernel option).
That's all I can think of,
The only other thing I'd mention is enabling kernel laptop support, for toshiba, sony and dell laptops, if you have one of those.
