Hi,

somewhere between revisions 1.15 and 1.22 of
src/sys/arch/i386/i386/est.c EST stopped working on my IBM ThinkPad
X40 using a Pentium M 738:

cpu0 at mainbus0: (uniprocessor)
cpu0: Intel Pentium M (Dothan) (686-class), 1395.54 MHz, id 0x6d6

                                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

EST worked fine with revision est.c:1.15 and earlier:

[...]
cpu0: Enhanced SpeedStep running at 1400 MHz (1116 mV)
cpu0: Enhanced SpeedStep frequencies available (MHz): 1400 1300 1200 1100 1000 900 800 600
[...]
