:hw.acpi.cpu.cx_lowest: C3

:hw.cpu0.cx_lowest: C3
:hw.cpu0.cx_usage: 0.00% 2.01% 97.98%
:hw.cpu1.cx_supported: C1/1 C2/1 C3/17
:hw.cpu1.cx_lowest: C3
:hw.cpu1.cx_usage: 0.00% 1.30% 98.69%

:Default cx_lowest is C1, you have to change it with sysctl(3). You can 
:change it per cpu (hw.cpuN.cx_lowest) or for all CPU's (cores) at once 

    Very cool.  I'll have to find a machine to test it on.  My test cubes
    only seem to have C1.
