What version of NM are you running?  You'll want whatever is in
F9-updates, which should be svn4022 or later.

nm-system-settings reads ifcfg files and if those files are minimally
valid provides those connections to NM, which uses them.

If that's not working for you and you have latest F9 updates installed
(again, svn4022 or later) then I'd love to see your ifcfg-eth0 file.
Please send and I'll be sure to fix whatever's wrong!

Looks like the system settings service can't parse the ifcfg file; and
if there aren't any valid ethernet connections on the system (unmanaged
devices are counted as valid) then nm-system-settings provides an "auto
ethernet" connection so that you'll at least get some connectivity when
you plug in the cable.
