I found 5 PRs regarding this symptom. On my 5.3-STABLE server, patch
attached with PR 17800 solved the problem.

For information, Tyan S1867DLUAN Thunder 2500 dual Slot 1 motherboard
always shows correct CPU usage on FreeBSD 5.x since early 2003, its
Socket 370 alternative S2567U3AN Thuder HEsl shows incorrect  on
5.3-BETA4 and recent 5.3-STABLE without patch.
