I doubt that it is network manager, because it is not installed. It was
uninstalled automatically when I installed wicd. Yet the problem

However, your first point (A) strikes a chord. At home my house is
wired for gigabit ethernet, so I have no wireless at all. When I get
home I put the T61 in its mini-dock and the network is "just there." 

So how do I find out if I have two DHCP daemons running in parallel? I
suppose I'd have to be at the university or somewhere connected via
wireless to see, since I am sure the wireless is not running at home
(never get disconnected at home). Is there a command line tool I can
use to see if I have two daemons running? (Note that I am a dummy about
such things.)
