I personally find this very interesting indeed.

After digging around, I locate the origin as 'cpuid()' functions.
Here, please answer a few questions:

1) What's your CPU option in kernel configuration file: I686_CPU
or I386_CPU? I guess yours is I686_CPU.

2) What's the specific model of your CPU? AMD Duron or Athlon?
What's the speed?

With your these answers, I could write a small patch. If you're
willing to try that, let's see how it goes.

Cheers,
Bin
