 I've been thinking about this and previous debugging attempts.  Switching
 to a serial console defeats all debugging attempts as the video console
 seems to be ignored (screen goes black) and the boot otherwise succeeds.
 
 There needs to be a way to keep the video console, but duplicate all
 messages on what would otherwise be the serial console (com0/tty00).
 This is particularly necessary when using DisplayPort as the monitor
 connection.
