Please excuse the top posting but this email client is awkward.
I saw a laptop file system shoot-out, unfortunately I've no idea what the
link is but it was high up in google. The guy compared JFS, XFS, Reisier
and the exts. Resiser came out on top for battery life when he ran various
tests, and he didn't use notail or noatime options. So I would go for this
one because I would definitely like the journalling on a laptop, like
Jonathan says.
Enlightment is my favourite wm but the pager polls the desktops by default
to keep the fancy pager display up to date. This would need to be turned
off for maximum power saving, or could be set so it doesn't update unless
the window is in focus.
I must try using framebuffer instead of X, didn't know you could do that it
sounds interesting! I love X for networking but I hear that work underway
to create a faster display solution? Is this the way to go? Last I heard
development seemed very fragmented on the alternative to X issue.

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.

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.

My Notebook is to old for ACPI *g*.

I use gentoo-sources, but don't ask me why. I couldn't give a solid
reason.
> 5) Framebuffer or not ?

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.
