[elrepo] LAN driver install w/o network?

Resolved (sort of).

I had to manually create /etc/sysconfig/network-scripts/ifcfg-eth0 and do an
ifup eth0.

If I had to guess, this situation arose because the NetworkManager service
is dead and I suspect the NetManager service is dead because when CentOS 6.0
was first installing, it couldn't find the device driver for 1969:1083 so it
went fishing.  Installing the driver for 1969:1083 and doing all kinds of
reconfiguring/rebooting didn't revive NetworkManager.

Here's the console log that I get when bringing up eth0 now.
