Yup.  If you do:

INET_ADDR=`/sbin/ifconfig ppp0 | grep "P-t-P" | cut -f 1 -d'P' | cut -f 2 -d ':'`
route add default gw $INET_ADDR

Stick those two lines in your pon script (assuming it's suid root already)
and away you go.  If the pon script isn't suid root, you'll need to
put these lines in a dedicated "setroute" script that _is_ suid root.
