^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

It seems your CPU is actually running at 133 MHz. If I am right, the
bogomips value should be about 2x the clock frequency on this CPU and
kernel. Is the bogomips calculation influenced by the detected CPU speed ?
Can't check now.

Can it be your system runs in a low-power mode, or that the linux kernel
triggers a low-power mode ?
