A fourth option, since you are upgrading from a working system, is to build
a kickstart floppy or cd image that does the upgrade completely unattended
correctly, then extract the kernel and initrd from the boot image, and install
them into lilo.  Then use the lilo -R option to set that image as the default
for one boot, and reboot the machine, when it comes back up it will boot the
upgrade image, upgrade itself, and then reboot to the new default kernel.
