Unsurprisingly (IMO anyway), ofwboot.elf behaves exactly the same.
But thanks for taking an interest!

On the way to trying Martin's suggestion of installing from a
diskless NFS setup, I hit a stumbling block I was not expecting:
9.3 does not see the machine's keyboard, so I can't type anything.
I tried 9.2 with the same result.  However, HEAD from a few days
ago does recognize the keyboard, so I guess it's going to be
bleeding edge for me.

Looking at HEAD's dmesg output, it looks like the keyboard path
is uhub2 -> uhub3 -> uhidev2, while 9.3 fails to notice uhub3
and therefore also not uhidev2.  I wonder if somebody fixed things
for nested USB hubs and didn't back-port.
