As an experiment, Gene, what happens if you comment out or remove the "search files, dns" (or whatever the exact syntax was) line in your /etc/resolv.conf file? Do /etc/hosts lookups stop working? If they do, this is *huge* news, and I'd love to have all of the relevant information to be able to reproduce this result, so that I can begin to understand it. If they don't, well, you know what that means.
