With ACPI "smart" batteries, we're currently spending long enough on
querying batteries that people are losing keystrokes. The same is true
of several crummy APM implementations. On the other hand, I agree that
it makes sense to leave polling in userspace rather than the kernel.
Once we go tickless on portable hardware, there's going to be a pretty
huge incentive to fix userspace in any case.
