I have no reason to think the newer iBook doesn't have a PMU; apple
would have to invent something totally new and then write support code
for it; not really their style.
I ad been avoiding writing APM-mode code since APM is so x86-centric,
and since there are other platforms that could use a more generic
battery management interface (and there's ACPI-mode battery code on
newer PCs, too).
