config CPU_FREQ

help
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 CPU_FREQ_24_API
bool "/proc/sys/cpu/ interface (2.4. / OLD)"

help
This enables the /proc/sys/cpu/ sysctl interface for controlling
CPUFreq, as known from the 2.4.-kernel patches for CPUFreq. 2.5
uses /proc/cpufreq instead. Please note that some drivers do not
work well with the 2.4. /proc/sys/cpu sysctl interface, so if in
doubt, say N here.
