If you (or someone else more kernel design experience than I)
redesigns and reimplements the msgbuf setup as you describe,
I can redo the commit in a less "replicating" manner.

OTOH, we're really only talking about adding printing of
copyright by the statement
	printf("%s%s", copyright, version);
in the Machine Dependent (MD) cpu_startup() invocations, where
we already have MD-specific printfs to display the version,
cpu_model, total & available memory, etc.
Arguably all of these could be moved into common code as well,
but that involves careful consideration of the MD requirements
in determining this information.

Cheers,
Luke.
