Exactly.

Okay, then go and make it better. Currently, I think lvcool is most
efficient then kernel-based solution, kapm-idled. LVcool takes all the
remaining CPU time, but kapm-idled seems to be interupted very often, so
the real idle time where HLT-commands or the ACPI-modes can be entered
is not as large as using an active user-space program.

LVcool exists if it does not detect the right chipset.

There is a patch, based on LVcool, apparently using the same idle time
slices which kapm-idled uses. Result: see above.

If you don't like it, don't use it. I won't force you to, of course.
