Well, spoke too soon, seems I had a run of good luck with netconsole 
loading early.  No longer true.  Need to figure out how to get this working:
$ systemctl status fedora-loadmodules.service
fedora-loadmodules.service - Load legacy module configuration
	  Loaded: loaded (/lib/systemd/system/fedora-loadmodules.service; static)
	  Active: failed since Mon, 17 Oct 2011 13:36:20 -0400; 16min ago
	 Process: 632 ExecStart=/lib/systemd/fedora-loadmodules (code=exited, 
status=1/FAILURE)
	  CGroup: name=systemd:/system/fedora-loadmodules.service


Sorry for the noise.
