Well, it's not a tool and it cannot print to terminal but you might want
to try out the bash skript below. It depends on media-gfx/graphviz to
create a postscript file visualizing the dependencies. The file will be
opened by your default postscript viewer (evince, okular, etc.).

Hope this helps,

psFile=$(tempfile --suffix=.ps)
lsmod | tail -n +2 | awk '{print $1,$4}' | tr ' ,' ' ' |
(
  echo 'digraph modules { rankdir=LR; '
    while read line; do
      dependencies=( $line )
      dependingOn="${dependencies[0]}"
      unset dependencies[0]
      for dependant in "${dependencies[@]}"; do
        echo "\"$dependant\" -> \"$dependingOn\";"
      done
    done
    echo '}'
) | dot -Tps > "$psFile"
xdg-open "$psFile"
unlink "$psFile"
