Actually another user has just reported [1] that his e1000e card got 
screwed up exactly at the point when the installer was probing the X 
configuration. So this really seems a lot like some lethal interaction 
between intel graphics and the network card.

Dave (Airlie, too many Daves on CC here really), do you by any chance see 
any recent change in kernel intel graphic parts of DRM be causing this 
breakage?
