+CONFIG_CPU_FREQ_24_API
+  This enables the /proc/sys/cpu/ sysctl interface for controlling
+  CPUFreq, as known from the 2.4.-kernel patches for CPUFreq. Note
+  that some drivers do not support this interface or offer less
+  functionality. 
+
+  If you say N here, you'll be able to control CPUFreq using the
