:The patch brings in the latest acpi_cpu(4) code from FreeBSD adapted for 
:DragonFly and our (old) acpica. This allows modern CPUs to use higher C 
:states than C1 which as result makes a laptops with these CPUs run MUCH 
:cooler (tested and measured ;).

    This looks great, Hasso.  I agree re: ACPI-based power handling.  It
    never worked right and isn't used for SMP anyway (there is no working
    idle hook for SMP).  A framework based on load and explicit throttling,
    instead of idle-throttling, is the better way to go anyway.
