As far as the BogoMIPS figures goes, the expected value is ~53.
My little Pentium 133 gives the following, so your P133 beats my
"GenuineIntel" chip.

    Calibrating delay loop.. ok - 52.84 BogoMIPS

Benchmarks are always fun, but compiling the kernel is a good rough
comparision:

time -o compile.time make dep clean zImage > compile.log 2>&1
cat compile.time
413.79user 28.85system 8:56.11elapsed 82%CPU (0avgtext+0avgdata 0maxresident)k
0inputs+0outputs (166662major+164574minor)pagefaults 0swaps

If you would like, I can send you the .config and so you can try the
same compile of a 2.0.35 kernel.

Yours sincerely,
