  Log:
  Fix a minor bug in the auto-console selection (handle the -m mute option
  properly).
  
  Detect when the serial port is unmapped (reads 0xFF) by putting a limit in
  the flush code and returning a testable value, then refuse to automatically
  configure it if so because an unmapped serial port always looks like it has
  input pending.
  
  This fixes a dual-console issue with laptops that don't map the serial port
  during the boot stage (e.g. my emachines amd64 laptop).
  
  Be ultra conservative for now, do not try to initialize the FIFO.
