 Log Message:
 Fix PR kern/43765 from Scott Ellis.
 
 Note that the solution is not optimal. If ichlpcib(4) provides SpeedStep
 support, possible I/O resource conflicts may occur with acpicpu(4). Ideally,
 as noted for instance in Windows design documents, ichlpcib(4) should never
 expose SpeedStep when ACPI is being used. The probability for potential race
 conditions is however very small, being limited to few P4-era machines and
 being dependent on user actions.
