How about a 556 timer that momentarily presses SHIFT+RUN/STOP a few seconds 
power is applied? Isn't there a patch that loads the first program on disk
instead of tape?

.. exactly. Here comes the more tricky part. Unless you want to make a
custom KERNAL too.. /me thinks. I don't really see a way (putting aside how
to distinguish between "normal" and "power-up" reset conditions) to do it
only with BASIC ROM changes and keeping its all functionality.
