Are you sure that misc/raspberrypi-userland is not able to be built on
NetBSD/aarch64 if you add NetBSD-*-aarch64 to the ONLY_FOR_PLATFORM line
in the Makefile? The original package is fairly old and may predate
64-bit capable RPi models.

You are also still talking to a 64-bit kernel running on a RPi4, which
has a different GPU to that on the original RPi models, so it might not
work whether built as a 32 or 64 bit package.
