What about mapping the bootblock to the ROM window below 1M as was
discussed some time ago? I know it does not exactly look like fun, but
AFAIK all recent and ancient chipsets mirror the top 64k there.
P.S. I'd just say that calling console functions from during the ROM
mapping is illegal. It's our code, we get to specify what is run.
