| Pentium M 730 runs with a 533MHz FSB, so the frequencies are

The first was from the est driver itself (it prints the mV and the
freq. at boot: cpu0: Enhanced SpeedStep running at 1200 MHz (1308 mV))
and the second one is on the datasheet available from Intel, but it's
the only one.
Like I said, the frequencies are most likely not correct.
