It even works without, you can use a script to provide the data:

/etc/mrtg.cfg:
|######################################################################
|# Multi Router Traffic Grapher -- Sample Configuration File
|######################################################################
|# This file is for use with mrtg-2.5.4c

|# Global configuration

|Title[ppp0]: router ADSL connection
|PageTop[ppp0]: <H1>Traffic analysis for ppp0</H1>
|Target[ppp0]: `/usr/local/bin/routerstats`
|MaxBytes1[ppp0]: 96000
|MaxBytes2[ppp0]: 16000
|WithPeak[ppp0]: wmy

/usr/local/bin/routerstats:
|#!/bin/sh
|IN=`cat /proc/net/dev | awk 'index($1,"ppp0") != 0 { print substr($0,8) }' | awk '{ print $1}'`
|OUT=`cat /proc/net/dev | awk 'index($1,"ppp0") != 0 { print substr($0,8) }' | awk '{ print $9}'`
|if [ "$IN" = "" ]; then IN="0"; fi
|if [ "$OUT" = "" ]; then OUT="0"; fi
|echo "$IN"
|echo "$OUT"
|uptime
|hostname

And I know my usage of awk is awkward here (^__-)
(It has been quite some time since I wrote that script...)
