Yes, (save-application ... :prepend-kernel t) does the trick.

Doc could be improved.  The documentation for function save-application ( no information about prepend-kernel nor any other of these keyword args:

 (purify t)  impurify  (mode #o644)  prepend-kernel

The text of this chapter leading up to the function does, in retrospect, explain the wonders of prepending the kernel in a somewhat chatty and roundabout style while managing to never actually refer to the PREPEND-KERNEL arg by name.
