I'm using 2.4.x and 2.5.x kernels; no special version.=20

A few pointers:
You might want to check /proc/sys/kernel/powersave-nap is "1".
Any suspicious messages on bootlog? (Post if in doubt)

What CPU does it have (post /proc/cpuinfo).
What clocks does it support according to /proc/cpufreq?
What does the pmu say? (see /proc/pmu)
What does the APM emulation say (need to run pmud to get reliable
results)?
Are the infos from the battery accurate? I need to completely empty
the battery without pmud every now and then to make the infos realistic.

Normally Motorola cpus turn of unused units to save power,
you might want to check that your system is really idle;
when running setiathome for instance my notebook also gets
warm and the battery is draining much faster (intersting=20
fact actually, since common belief is that the current drawn
by processor is far less that the sum of all other components).
