Yes, Sep 1 is modern enough.

With g_ether not compiled in i see only 4 messages on boot and i'm sure
they can't slow down the boot considerably.

Nah, it doesn't print anything on suspend/resume.

Go ahead, but i very much hope you wouldn't be able to convince anybody to
make it default.

You != everybody

I won't. 285 dpi that our displays have can't be unsharp.

Somehow i do not (except when something is going wrong, but it happens only
once, after that the messages don't take time to be outputted, because no
scrolling is involved).

So i'm waiting for something that can in fact help to find and fix the
messages in case they're really inappropriate.
