bsd does not recognize cpu-usage

[Martin Schmitz <martin-schmitz@web.de>]

Hi all,
I installed OpenBSD 3.0 on a Celeron 366 Notebook form
Acer. Everything went fine, except for the fact, that the kernel
doesn't seem to be able to recognize the amount of cpu usage. Even if
the system does some compilation tasks, top, xosview and all the other
tools are showing a cpu-usage of 0.00%. With OpenBSD 2.8 it was the
same.
Does anybody know this phenomena? Is it a bug, or is it a question of
the proper kernel-configuration?

thx in advance,
Martin
