Hmmm....
I don't know if this is the intended operation or not (probably a question 
for the Linux tree dudes), but...

Kenneth's 486 reports at about 1/2 the clock speed (also notice the lack of a 
cpu MHz line in the report).

This Celeron reports at about 2* the clock speed. (Kernel 2.4.17)

If memory (mine) serves, my P-II system reported at appox. bogomips == cpu 
clock.  I don't recall what my Pentium or 386 system reported and have never 
had a 486.

I think I noticed the change in the relationship between bogomips and cpu 
clock early in kernel 2.2.x (while I was running the P-II system) - perhaps 
something has crept in from the Linux tree that is having this effect.
