    No, I used the same .config in all versions that I tested. I've also
    tried setting them as modules rather than built-in. This is the stock
    slackware .config:

    CONFIG_CPU_FREQ=y
    CONFIG_CPU_FREQ_TABLE=m
    CONFIG_CPU_FREQ_GOV_COMMON=y
    CONFIG_CPU_FREQ_STAT=m
    CONFIG_CPU_FREQ_STAT_DETAILS=y
    # CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set
    CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y
    # CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND is not set
    # CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set
    CONFIG_CPU_FREQ_GOV_PERFORMANCE=m
    CONFIG_CPU_FREQ_GOV_POWERSAVE=m
    CONFIG_CPU_FREQ_GOV_USERSPACE=y
    CONFIG_CPU_FREQ_GOV_ONDEMAND=m
    CONFIG_CPU_FREQ_GOV_CONSERVATIVE=m

    And modprobing any governor module does not change the output of
    scaling_available_governors.
