Motherboard:  ASUS P5A-B ACPI Bios Rev 1011 (current for this board)
CPU:  AMD-K6-III/450

sysctl kern.clockrate reports hz=1000, tick=1000, profhz=1024, stathz=128

kernel recompiled to include CLK_USE_I8254_CALIBRATION and the condition does not change, nor does the output of sysctl.kern.clockrate

>How-To-Repeat:
use date command.  wait exactly 1 minute. use date command.  Elapsed time will show 2 minutes have passed on the computer.
