This looks like you're using dhcp. A few of us are working on some
updates to the dhclient-script that ships with the system, but for now you
can comment out all the route commands that add routes for 127.* in
dhclient-script and that should solve your problem.
Alternatively you can take a look at the attached diff, which
contains most of my work in progress. There are one or two things that
need to be finished (pending some confirmation to my changes that will be
provided next time that my stupid ISP hard resets their DHCP server) but
this will give you an idea as to where I'm heading.
Good luck,
Doug
