The values reported by cpufreq are the values the CPU is supposed to run
at, that is the hardcoded FSB speed mutliplied by the "multiplier factor".
If you modify the FSB (and not the multiplier), this isn't detectable by
cpufreq. However, if you modify the multiplier, you'd need to override the
PSB or ACPI tables, and the frequency table helpers are the wrong place to
look for that.
