When I used FC4 on my old IBM X40 (Intel Pentium M Ultra-Low Voltage
CPU, clocks from 1.00GHz down to 266MHz) I had to jump through a bunch
of different hoops to get CPU frequency scaling working correctly.
Once I got that working the machine used a lot less power.

There was some cpufreq utility that needed to be installed to make the
cpufreq LKM available.  Then I needed to run some obscure "insmod
cpufreq" command as root.  That was FC4, it could have changed.  It
might also vary based on CPU.  I seem to remember my chip not being
included in the default set of frequency scaling chips.

If there's a "laptop" kernel or a "laptop-mode" package you might want
to install that.  I remember a situation (can't remember the distro)
where simply installing a package named "laptop-mode" roped in a whole
bunch of goodies as well as configuration files that enabled them.

Good luck!

Also likely candidates for such a poor battery life:
o The hard drive might not be spinning down while not in use.  There's
some setting you can use in /etc/fstab to change this.  Try reading
through man fstab for more details.
o The CD drive might be goofing off.  If there's a disk in there,
that'd be a good suspect as well.
o The wireless card might be using inoptimal power management schemes.
