786           This allows you to replace the boot message indicating the kernel version
787           and the driver version with a custom message. This is useful on appliances
788           where a simple 'Starting system' message can be enough to stop a customer
789           from worrying.
790 
791           If you say 'Y' here, you'll be able to choose a message yourself. Otherwise,
792           say 'N' and keep the default message with the version.

804           An empty message will only clear the display at driver init time. Any other
805           printf()-formatted message is valid with newline and escape codes.
