--- Comment #1 from Ed Maste <emaste at freebsd.org> ---
Thank you for your contribution!

Unfortunately just removing the SetMode is no good, because with other UEFI
implementations the display is not set up correctly for us at boot and the
loader output does not work w/o it.

As you point out we should handle the case that ConsoleControl is not
implemented (we just skip the SetMode if LocateProtocol fails), so this
suggests that the failing systems here implement a broken ConsoleControl.

It looks like we may need a blacklist of broken systems (or a whitelist of
systems that implement & require ConsoleControl).
