Were you on AC or battery when you booted? 

It seems that the T30 (and many other laptops from multiple vendors)
does not change the CPU speed when APM/ACPI from FreeBSD tells it
to. If I boot on battery, my system stays at 1.2 GHz and if I boot on
AC power, the system runs 1.8 GHz. Changes to the power source made
after it is up seem to have no effect.
