What's wrong about this? You CPU does 2.5 x 66 MHz = 166 MHz -> you should see about 165 BogoMips ... CPUID seems to be off by default on your CPU, though I was believing 6x86MX has it turned on by default. Strange. That's why you CPU family of 4.

And this is the consequence of cpu family == 4.
I remeber having read a posting, where somebody claimed that egcs optimizes some routines for CPU recignition which causes the 6x86 not to be detected correctly. Don't know if this is the case for you. I also remeber that it only happened with kernels configured for 586 and 686. ?
