 First of all, the PR was created improperly - sysctl -a output is in "Fix"
 section for some reason.  Please don't do that in the future.
 
 Second, it's impossible to tell if "C2 and C3 states should probably be
 available" unless we see acpidump -dt output and dmesg with ACPI debugging
 enabled (ACPI_PROCESSOR x ACPI_DB_INFO):
 http://www.freebsd.org/doc/handbook/acpi-debug.html
 
 P.S.
 That is, generally we expect to see C2 and C3 levels, but not universally.
 BIOS or BIOS configuration, motherboard peculiarities and OS supported features
 are among the thing that affect C2+ availability.
