the answer is .... yes and no :)
You CAN use the serial port for comm stuff. Simply don't launch
the getty disabling it in the /etc/inittab file, and the ttyS0 device
is free for your application.
You CAN eliminate the ton of kernel messages modifying the file
related to the 68328 serial driver
disabling the console_print_68328 function AND the wakeup of driver
about ^P and ^R "magic" characters.
You CAN'T completely eliminate the messages on boot. The bootloader
will show *always* its startup message, and this is a fact of life :)
