With the new generic console code, that would be pretty easy to do.
Just clone lp_char, or add an argument, so that it always uses polling
and never reschedules (but does time out) and register that function
as a console print function.
Then boot with the arguments "console=tty0 console=lp0" and see the
boot messages appear on your printer :)
