I've moved towards always initializing matplotlib explicitly in the
notebook myself, because that way:

1. the notebook is fully self-contained and doesn't depend on how the
server was started
2. the server doesn't start *every* kernel with --pylab, letting me
choose when I need matplotlib and when I don't.

Since in your case all you need is a tiny bit of logic to do 'import
matplotlib; matplotlib.use("agg")', I suggest you either do it
explicitly at the start of your notebook, or put it into your startup
profile.  It's too much of a small corner case to warrant messing with
our already quite convoluted pylab integration machinery.
