    [CPUFREQ] Kconfig powernow-k8 driver should depend on ACPI P-States driver
    powernow-k8 really needs to use ACPI to function on SMP systems.
    The current Kconfig allows us to build kernels which fail mysteriously
    for some users due to us trying to automatically enable this, and
    getting it wrong.  It's easier to just present this as an option
    to the user.
