This is how it should be. Read the BogoMIPS mini-howto.

<snip>
As a very approximate guide, the BogoMips can be calculated by:
Intel Pentium II clock * 1.00
Pentium MMX clock * 2.00
</snip>

BogoMIPS is not a measure of how fast your computer is, it is
just used for a delay loop used by the kernel. Every type of CPU
has a "BogoMIPS = clockspeed * some constant", so you shouldn't
use it to compare different CPU families.
