cpufreq_ondemand no longer in filesystem after upgrade to kernel 3.9.2

As the title states the cpufreq_ondemand governor is no longer available. powerdown complained it cannot write ondemand /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor. I then checked lsmod and noticed that acpi_cpufreq is not loaded. Running modprobe acpu_cpufreq gave me this:

modprobe: ERROR: could not insert 'acpi_cpufreq': Device or resource busy

Also,  ls /lib/modules/$(uname -r)/kernel/drivers/cpufreq

show this

[christian@christian ~]$ ls /lib/modules/$(uname -r)/kernel/drivers/cpufreq
acpi-cpufreq.ko.gz          cpufreq_stats.ko.gz      p4-clockmod.ko.gz  speedstep-lib.ko.gz
cpufreq_conservative.ko.gz  cpufreq_userspace.ko.gz  pcc-cpufreq.ko.gz
cpufreq_powersave.ko.gz     mperf.ko.gz              powernow-k8.ko.gz

 

Anyone else? Do I have to manually download the module?

Also, ondemand and performance are built-in, not modules:

#
# CPU Frequency scaling
#
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=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 is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=m
CONFIG_CPU_FREQ_GOV_USERSPACE=m
CONFIG_CPU_FREQ_GOV_ONDEMAND=y
CONFIG_CPU_FREQ_GOV_CONSERVATIVE=m

Re: cpufreq_ondemand no longer in filesystem after upgrade to kernel 3.9.2

how did I miss that thread. Ok, so I should probably just comment the frequency scaling lines out f powerdown and powerup right?
