I didn't hear back from anyone, and ended up with a second apu2, that I
felt comfortable trying this on before it was in service.

  Under NetBSD 9, using flashroom 1.2 to update an apu2 was
  straightforwardly successful.  (I had to override the name match just
  as the instructions say, but that's not related to host os for
  flashrom.)
    flashrom -w apu2_v4.13.0.4.rom -p internal:boardmismatch=force

  I used
    pcictl /dev/pci0 write -d 24  0x6c 0x580ffe10
  to force a cold boot, adapted from FreeBSD instructions.

and in the end this was an entirely unexciting experience, for which I
am grateful.
