Very good troubleshooting!  It is a 'feature' of the 2.2.x kernels.
The kennel now does the routing itself so the route command in the
network script isn't needed.

Here is how I changed my /etc/init.d/network script to handle it

if [ $(uname -r  |grep 2.0) ]; then
        /sbin/route add -net 127.0.0.0
        ifconfig ppp ${IPADDR} netmask ${NETMASK} broadcast
${BROADCAST}
        /sbin/route add -net ${NETWORK} netmask ${NETMASK}
else
        /sbin/ifconfig lo 127.0.0.1
        /sbin/ifconfig eth0 ${IPADDR} broadcast ${BROADCAST} netmask ${NETMASK}
#####       /sbin/route add -net 127.0.0.0 netmask 255.0.0.0 dev lo
fi

Hope This Helps
