Attilio, I csup-dated several hours ago and rebuilt and installed the kernel (and world, in case it matters).

%uname -a
FreeBSD free.bsd369441.org 8.0-STABLE FreeBSD 8.0-STABLE #0: Thu Apr  8 03:01:13 EEST 2010     root@free.bsd369441.org:/usr/obj/usr/src/sys/GENERIC  amd64

The problem persists without the machdep trick, I see only one processor in top with 0.0% CPU load.
