Right. I suspect then that the following commit may be the cause of the
regression:

Revert "speedstep-lib.c: fix frequency multiplier for Pentium4 models 0&1"

That would exactly explain the factor 8 of the error.

Do you have a line like the following in your debug output?
P4 - FSB %u kHz; Multiplier %u; Speed %u kHz\n
If so, what does it say for .24 and .28?

Can you please provide the output of 'x86info -a' (as root) after loading
the cpuid module?
