How to direct the boot output to COM1 at 9600 baud AND allow login.
Edit /boot/grub/gub.conf
Add serial --unit=0
Add terminal --timeout=15 serial console
Comment out #splashimage=(hd0,0)/grub/splash.xpm.gz
Comment out #hiddenmenu
Add console=tty1 console=ttyS0,9600n8 to end of each kernel line
Example...
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/main/root
# initrd /initrd-version.img
#boot=/dev/hda
serial --unit=0
terminal --timeout=15 serial console
default=1
timeout=15
#splashimage=(hd0,0)/grub/splash.xpm.gz
#hiddenmenu

Make following configuration changes....
db configuration setprop BaudRate 9600 Device ttyS0 status enabled
expand-template /etc/securetty
signal-event halt
Connect proper null modem cable to COM1 and to 'other' machine. Configure terminal program(minicom) on 'other' machine for 9600n1.
Power up SME machine.
The above has been working for me for some time now.
SME still contains a video card.
