I asked David Green about this a couple years ago -- at that time the
FreeBSD crew had the kernel divided into at two locks: one for I/O and
one for everything else.  but that was then...  the "SMPng" project is
heading towards much finer grained locking.  they have a status page at
http://www.freebsd.org/smp/index.html .

of course I'm sure that when the time comes the analogous NetBSD
implementation will be just as good, run on half a dozen different
multiprocessor platforms, and have elegant readable code to boot.  :)
