People have started using my trace-printk notice message, that seems to be big enough to get noticed.
********************************************************** ** NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE ** ** ** ** trace_printk() being used.

There's been some talk about making that a more "generic" warning message too.
