So, this worked, Toni Willen (of WinUAE fame) figured out these new
Kickstarts do not initialize console.device before bootstrap is called,
and then Thomas Richter (of MMULib, P96, "modern Kickstart", etc fame)
proposed a workaround which I implemented, and it seems to work.

Patch here:

This made the bootblock work for me on KS v47.102:

The patch works like this: if opening "console.device" fails, it tries to
initialize the "console.device" ROM module using FindResident and
InitResident, and then open the device again. For older Kickstarts, the
code is practically unchanged, because there the first opening already
works. For newer Kickstarts, this works around the initialization issue.
