I think the SA1100 serial driver doesn't correctly behave like a real
console. If I compile with "Console on SA1100 serial port" and without the
frame buffer device, I always get the message "Can't open initial
console". I've put some printk("Now here") messages in the kernel to find
out where the messages remain, but they aren't printed on the serial
port, although they are available with the "dmesg" command. OTOH, kernel
oopses generated on ttyS1 are verbosely reported on ttyS0.
