The clock is initially set up in the bootloader, so the answer to this
will depend on the bootloader you are using... 

On a running system, /proc/scale/ can be used to change the clock speed

'echo 5 > /proc/scale' should set the clock speed to 133 MHz (or maybe
it just halves it? - i can't remember).
