Drop the default running value to 60% from 80%. Testing shows that we
...
cycle too much, wasting power if we trigger a jump to full speed too
easily. CPU-bound tasks quickly push idle below this level.

Add support for recording the total energy used (in joules) when in
...
verbose mode. This is useful for profiling new adaptive algorithms
in performance (via time(1)) and total energy consumed for a given
workload.

Move the AC line checking code into its own function, reducing the
...
ifdef __i386__ stuff for APM. Tested as working correctly on i386 and
compile-tested on sparc64.

Unbreak !i386 platforms. Only i386 has APM, so don't try to fallback
...
on APM on other platforms.

Change the default levels for adaptive mode to 80% and 90%. On a system
...
with moderate IO going on, system usage can hover around 65-77% even
though it would benefit from higher performance. Typically, only truly
idle systems pass the 90% mark so only demote then.

Import powerd(8), a utility for managing power consumption. Currently, it
...
just uses cpufreq(4) but in the future it should also do things like spin
down disks. This is based on the work by Colin Percival (called "estctrl").
