try to start it without this.

ab226d7010 Ignore EPERM from sysctl(3). It is returned when passive cooling
is active.

ef01f96275 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.

46d7cfdb4b 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.

a59663d2e5 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.

3ebf74b8a8 Unbreak !i386 platforms. Only i386 has APM, so don't try to fallback
on APM on other platforms.

2347ac87e8 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.

3960f7cce3 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").
