Hmmmm. I was thinking that the serial port only got into the picture
after the kernel was loaded and / was mounted so /etc/ttys could be
read to configure the console, but you remind me that it comes into
play during a mid-phase of the boot loading. So what I'm looking for
would require a considerable change to the boot loader. I wonder if
it has to fit into a few (up to about 15, IIRC) boot records, or if it
could use some code under /boot/? Oh well, you've convinced me that
Ethernet consoles can't be easily supported (though it still seems
useful enough that someone would have done it by now). Thanks.
