+CONFIG_CPU_FREQ
+  Clock scaling allows you to change the clock speed of CPUs on the
+  fly. This is a nice method to save battery power on notebooks,
+  because the lower the clock speed, the less power the CPU consumes.
+
+  For more information, take a look at linux/Documentation/cpufreq or
+  at <http://www.brodo.de/cpufreq/>

+CONFIG_X86_POWERNOW_K6
+  This adds the CPUFreq driver for mobile AMD K6-2+ and mobile
+  AMD K6-3+ processors.

+CONFIG_ELAN_CPUFREQ
+  This adds the CPUFreq driver for AMD Elan SC400 and SC410
+  processors.
+
+  You need to specify the processor maximum speed as boot
+  parameter: elanfreq=maxspeed (in kHz) or as module
+  parameter "max_freq".
