Driven from Gentoo by fear of having to recompile everything all the
time?  Heh... me too.  I ended up on Fedora, which is interesting.  I
still remember enough of Kubuntu to not unsubscribe from this list
though.

Well, Gentoo is more efficient than Kubuntu by the very nature of it.
It's using binaries that are custom-fit to your laptop.  Kubuntu uses
less fine-tuned binaries, and thus uses more juice.  It's just a
tradeoff, though I'm positive there's a more elegant solution that
will fix your fan.  I just gave up and decided it's not worth my
effort (being a happy IBM X40 owner myself).

Yes, I have had it working (under Gentoo) and it now works under
Fedora (Core 6).  I never had it working to begin with under Kubuntu
(which I used before Gentoo) but that was because I was a total newbie
and couldn't tell a LKM from a java applet.

If memory serves, once you get the first problem solved (getting the
tpd/xosd things to work) the fn-f3 stuff all comes quietly after that.

Rebuild your xpm.gz image to the new resolution... I don't know,
really.  I'm horrible at making grub splashes (never figured out how
many colors it needed - really funny story) so your probably already
several lightyears ahead of me there.
