I think killing it completely is a bad idea. There are times when a
machine has bad hardware, but good enough to boot halfway up. Getting the
error messages then could be very helpful. Likewise, at runtime the RTAS
messages are also useful since they'd show up on the console (and in the
dmesg output in kdb).

But, as you said, at boot time there's normally limited use for them. If
they're killed, I want to see a command line option to enable them if
needed. I also don't think that post-boot output should be removed at all.
