The logic in stand/efi/loader/main.c:parse_uefi_con_out() seems to be
that RB_SERIAL is set when the serial device appears before the video
device in the ConOut efi variable, which is the case on a minnowboard
that I looked at. You can override this by setting boot_serial="NO" in
loader.conf or running `set boot_serial=NO` at the loader prompt.
