NM 0.6 or NM 0.7?  Both should be choosing the wired connection as the
default as long as the DHCP server is returning a gateway, or as long as
you've set a gateway manually if you're using static IP on the ethernet.

Can you post some logs from /var/log/messages so we can figure out what
NM thinks it's doing?  What specific NM RPM version is this with?

Likely a bug.

No, because that's not usually needed as long as there aren't any
bugs :)

If you like, you can send /var/log/messages to me privately if you're
concerned about something in the logs you'd rather not have public.
