The CPU frequency is measured! So, either the programmable interrupt
timer isn't getting the right clock frequency or the CPU isn't getting
the right clock frequency.
Since the reported bogomips is about twice the CPU frequency, the
measured numbers look correct. So, maybe the jumpers on the mother-
board (or the BIOS) are not set correctly??
