You could enable serial console -- then you'll get nothing until the
ttyv* terminals start up. But if something explodes, you'll have to plug
in a serial cable. :)

Killing the kenrel output is probably doable but removing output from rc
scripts is a bit more sizable task.

I've seen the boot so many times that I know when it looks wrong, but I'm
wierd and not a part of the redsplat generation.

There used to be a way of hiding the kernel boot behind a spash screen,
not sure if that still works.
