Any PPC binaries for FluxBox? I'm interested, but haven't done any of
my own compiling yet. Thanks for the rest of your info!

I have an iBook 700, I've also noticed that Linux runs hotter (and thus
louder) than OSX (or XP on an Intel laptop.) There are many reasons for
this. For starters, the HD doesn't spin down nearly as much. To fix
this you can do several things:
- Install bdflush
- Fiddle with hdparm to set the sleep delay
- Use Ext2 or at least set the write times for the Ext3 journal for
something quite large
- Disable any unneeded daemons (such as, I would argue, the cron and at
scripts.)
I suppose throttling the CPU back would help battery life qute a bit.
I'm not sure how this is done, but know it's possible.
Linux runs a lot of stuff in the background, any of these can wake up
the HD. With a lot of care, power management in Linux can be pretty
much what it is on OSX or XP, but it takes a lot of fiddling. FWIW,
I've found the PM stuff for Apple HW to be lightyears ahead of the PM
for Intel HW, it's one of the reasons I like the iBook so much as a
Linux box.

Hmmm.. big surprise! Yeah, probably just memory leaks/buggy software.
Have you tried something lighter like FluxBox or XFce? They are very
useable, stable and make Gnome and KDE feel like dogs. It's hard to
kick FluxBox's tabs once you get used to them.

Yup, this is normal. It's also quite normal for Linux to always use up
as much RAM as possible, it's just sitting there, so they might as well.
Cheers,
Ben
