Comment 5 for bug 156066

I have the same problem, /sys/devices/system/cpu/cpu0/cpufreq directory is missing. lsmod|grep freq shows that cpufreq modules are loaded.

dragonfox@kitsuden:~$ lsmod|grep freq
cpufreq_powersave 2688 0
cpufreq_stats 7104 0
cpufreq_userspace 5284 0
cpufreq_ondemand 9740 0
cpufreq_conservative 8712 0
freq_table 5536 2 cpufreq_stats,cpufreq_ondemand
