kldxref(8) in what you're looking for.

I personally recommend creating diskless roots by using install targets
rather then copying files around by hand.  For instance the following is
a script I use to create roots for testing (the ports stuff isn't
necessicary of course, but I included it because it's somewhat
intresting and some of the issues are non-obvious):

---<cut>---
#!/bin/sh

src=/usr/home/brooks/aero-p4/fellowship/roots/freebsd/5.2-CURRENT
dest=/usr/diskless/5.2-CURRENT.deptest
kernconf=NODE
ports=/usr/ports

# Rebuild the source
#cd ${src}
#make buildworld
#make buildkernel KERNCONF=${kernconf}

# delete the old setup
#rm -rf ${dest}
#chflags -R noschg ${dest}
#rm -rf ${dest}

# install a new world
cd ${src}
mkdir -p ${dest}
make DESTDIR=${dest} installworld
cd etc
make DESTDIR=${dest} distribution
cd ..
make DESTDIR=${dest} KERNCONF=${kernconf} installkernel

# install a copy of ports
# This copy of ports is assumed to be up to date with a correct INDEX.db file.
cp /etc/resolv.conf ${dest}/etc/resolv.conf
mount_devfs devfs ${dest}/dev

#cpdup -i0 -vv /usr/ports ${dest}/usr/ports
mkdir -p ${dest}/usr/ports/
rsync -av --delete --exclude=CVS /usr/ports/ ${dest}/usr/ports/
if [ ! -d ${dest}/var/db/pkg/portupgrade-* ]; then
        chroot ${dest} pkg_add -r portupgrade
fi
#chroot ${dest} portupgrade -a
chroot ${dest} portinstall -M BATCH=yes ganglia-monitor-core sge diskmark diskprep mail/postfix
mkdir -p ${dest}/usr/local/sge/default
/bin/ln -fs /usr/local/sge/default/common/rcsge
/usr/local/etc/rc.d/sge.sh

umount  ${dest}/dev
rm ${dest}/etc/resolv.conf
