They work fine for me and are detected automatically by MRTG.  See if they
may be detected but commented out in the mrtg.cfg for some reason.  MRTG
will usually pick up all interfaces and comment out with reason those that
the script determines should not be displayed.

Also note that Cisco sets the default bandwidth of tunnels to 9 kbits/s
which MRTG will pick up and set as the maximum speed.  So change the
router config to put something reasonable there or the graphs will generate
but not be very interesting.   :-)
