disabling warnings when booting w/o IPv6 in kernel (AKA postfix idiot question)

[Hubert Feyrer <hubert%feyrer.de@localhost>]

The other day, I booted a kernel without opsions INET6, and got a number 
of warnings (see below). I think it's be nice if they didn't show up in 
the first place. Is there a way to disable them when no IPv4 is found?
Funny enough, it's only postfix that complains...

This is on NetBSD 5.0/i386.
