FWIW, I've seen similar pagefaults, but they occur after the box has been up
for some time. The hardware in the box is suspect though, so I've just
attributed it to that. The panics seem to happen every few days. The box is
basically sitting idle, with the exception of running /usr/ports/misc/dnetc.
