No CPU utlization reported on SMP machine

I have been playing with -CURRENT and noticed issues with the reporting of
CPU utilization.

The %CPU column in the output of 'ps' is always 0.0.  The WCPU and CPU
columns in 'top' are always 0.0%, as are all the CPU state indicators.
CPU stats from 'vmstat' are always 0.

Machine:  Dual Pentium Pro 200 running -CURRENT with SMP, cvsup'ed and
rebuilt Dec 11.

Kernel conf:  basically stock with SMP enabled, but includes SCHED_ULE
instead of SCHED_4BSD.  WITNESS and INVARIANTS are not enabled, neither is
ACPI.

Any hints or suggestions?

I can provide further details...
