Don't know if this helps you or not but on my fresh gentoo install
(accidentally deleted var and opt with no backups) my "System Monitor -
Network" plasmoid is working correctly and I don't have knetworkmanager or
networkmanager installed. If you are using wired internet all you would have
to do is set it up in /etc/conf.d/net and it should be available to the kde
network monitor. I am running kde 4.2.4 atm.
HTH (or at least points you in the right direction)
