-3.2 Deprecated Interfaces

-Depending on your kernel configuration, you might find the following 
-cpufreq-related files:
-/proc/cpufreq
-/proc/sys/cpu/*/speed
-/proc/sys/cpu/*/speed-min
-/proc/sys/cpu/*/speed-max

-These are files for deprecated interfaces to cpufreq, which offer far

+The 'enable' file provides a counter that indicates how many times the device 
+has been enabled.  If the 'enable' file currently returns '4', and a '1' is
+echoed into it, it will then return '5'.  Echoing a '0' into it will decrease

 The 'rom' file is special in that it provides read-only access to the device's

 should write the string "1" to the file to enable it before attempting a read
