The version/copyright line is written before the configuration is
read.  This would require that you edit extlinux.asm to prevent it
from writing the text then recompile EXTLINUX.  The biggest issue with
such is that you will not know if anything works or fails until
something else outputs something to the console.

For this kind of a situation it may be easier to (by default) load a
COMBOOT/COM32 module that clears the screen (as simple as writing a
bunch of newlines) then runs another command that you pass to it.
This should be a simple extension of either my alias.c32 module or
Michael Brown's cmd.c32 module.
