hmm, I think I see some simillar problem with uniprocessor AMD K6-2 333Mhz
and kernel 2.3.40, but I'm not sure if it's a kernel problem or procps.

I have a niced process taking 100% cpu, and 'top' reports the cpu as 195.6%
nice and 840402.4% idle. If I suspend the niced process, the values goes
sane again.
