I don't know how much you care about my ancient hardware, but I got this
from the new clock calibration code when run on my 16Mhz 386sx:

May 15 13:02:44 stupid /kernel: FreeBSD 2.2-CURRENT #45: Wed May 15 01:06:31 EST 1996
May 15 13:02:44 stupid /kernel:     syssgm@stupid.devetir.qld.gov.au:/usr/src/sys/compile/STUPID
May 15 13:02:44 stupid /kernel: Calibrating clock(s) relative to mc146818A clock ... i8254 clock: 63817 Hz
May 15 13:02:45 stupid /kernel: 63817 Hz differs from default of 1193182 Hz by more than 1%
May 15 13:02:45 stupid /kernel: CPU: i386DX (386-class CPU)

and on a subsequent reboot:

May 16 17:01:33 stupid /kernel: 63814 Hz differs from default of 1193182 Hz by more than 1%

It only differs from the default by 95%. :-)
