+         CPU Frequency scaling allows you to change the clock speed of 
+         CPUs on the fly. This is a nice method to save power, because 
+         the lower the CPU clock speed, the less power the CPU consumes.
+
+         Note that this driver doesn't automatically change the CPU
+         clock speed, you need to either enable a dynamic cpufreq governor
+         (see below) after boot, or use a userspace tool.
