And me before him :)

To be clear I'm not blaming you in any way for this, the existing code is
terrible and incredibly fragile.

Yeah I agree it's easy to miss. And it's not part of dmesg (because it's from
prom_init()), so you *only* see it if you're actually staring at the console as
it boots (which is why my boot tests missed it).

I actually have plans to rewrite the whole thing to make it robust, so that
should avoid it ever being a problem again.
