Ah, init=/bin/sh, that's why you have /dev/console. I feared somebody again 
using /dev/console in inittab.

Guess that /dev/console is not a TTY, so that it not possible. I mean, you'd 
have to patch (uselessly) the very TTY core layer.

Or make Linux use /dev/tty0 instead of /dev/console when starting init - which 
is simpler. There is maybe even a console= switch

What about something like init="kludgy script which calls, say, a mixture of 
setsid, <> /dev/tty0, open(1) and such stuff to make sh start?

Maybe sh doesn't even need that, but login(8) needs setsid. I never remember 
the exact combination, however.
