I solved this thanks to NetBSD's excellent documentation. I happened to
notice an example in man 5 boot.cfg:
           # Disable Direct Rendering Manager (DRM) drivers
           userconf=disable i915drmkms*

Sure enough, adding that userconf to my boot.cfg solves being able to boot
NetBSD 10 without VGA connected, like it behaved in 9.3.

I'm certain I did not add that to my 9.3 boot.cfg for this machine, so
there is still the question of what could have changed from 9.3 to 10.0.
