If DDB/KDB is present and enabled you get a KDB printf before the
memory check delay. The kernel clearly can afford to do an "I'm
here!" message a little sooner than it currently does.
At times I wonder if we could add something early, like:
/* Test if the console is working yet. */
printf(" \\|/ ____ \\|/\n \"@'/ .. \\`@\"\n /_| \\__/ |_\\\n
\\__U_/\n");
