You need to tweak your /etc/dhclient-script to not set a default
route.   This should be configurable, but currently isn't.   Sigh.

If you are doing name resolution internally, you probably don't want
the client to install an /etc/dhclient.conf anyway.   In -current, you
can disable this (man dhclient-script for details), but in 1.3 you
can't.   The client in-current should build on 1.3, though.   The only
catch is that the -current Makefile is slightly broken on 1.3 and will
build shared libraries, which shouldn't really affect you, but wastes
some time.
