We too are having issues with the imaging driver for e1000e devices but our servers are on 10.3.1. Patch finder shows the latest update for 10.3.1 is "post October 2010" imaging update. The 10.3.3 imaging update seems to detect the network devices when using the bootcd. So the big question is, can we apply the latest imaging driver update for 10.3.3 to our 10.3.1 servers or will it cause issues? Option B is to update to the post October 2010 update and add the hardware with the newid trick.
