/etc/lilo.conf

image=/test_kernel/2.1.123
label=2.1.123-serial
optional
append="console=ttyS1,115200 mem=64M"

Check /dev/console

crw-r--r-- 1 root root 5, 1 Sep 30 18:27 /dev/console

I never had much luck with /etc/ioctl.save so I fudged it by adding to
the start of /etc/rc.d/rc.sysinit.

# Set up console, VT or serial console

80001cb2 is 115200, 80000cbd is 9600. Enjoy.
