The best thing is to isolate the unneeded parts all at once and go on
turning them on one by one.
Also, it would be useful if you could drop into single user mode to get
rid of all those Desktop Environment crap.

I'm not sure if parport on such a notebook is needed.

Unfortunately, the ondemand and conservative drivers most probably won't
work with your computer (it may complain about too high latency to
switch speeds---heck it even does that on my Pentium D 805).

Which filesystems are you using? Ext2? Ext3? You can drop the unneeded
modules.

I'm not really sure about lm75 on an Apple Mac.

Are you using any kind of redundancy (RAID) on your powerbook?

You seem to have many access to the disk. Perhaps, you could track down
what is using the disc with:
echo 1 > /proc/sys/vm/block_dump
(Warning, this may generate copious amounts of output!)

Those suggestions from powertop are very good measures to take if you
are chasing something that you don't really understand.
Anyway, I suggest that you think about the points that I listed above
(after all, you know your needs). There's no need to justify your uses.
I'm just bringing them to your attention.
OTOH, seeing if the fan is turned on even when you remove some modules
and in single user mode would help a lot (as root, run: "telinit 1").
Running powertop while in single user mode would also help.
