I have now found a beta version of Pi OS 64bit:
https://downloads.raspberrypi.org/raspios_arm64/images

Pi OS appears to support this special hardware better than Ubuntu, e.g.
graphics and CPU power regulation (less heating).

Consequently, I have rebuilt the polyml component in Isabelle/3e84f4e9651a; it
now works both with Pi OS (Debian 10) and Ubuntu 20.04.
