An alternative, from one of newsgroups, is to
create /etc/modules/cdrw containing

	# First, get the ide-cd drive to not latch onto /dev/hdd
	options ide-cd ignore=hdd
	#
	#
	# Set up an alias for /dev/scd0 to load sr_mod
	alias scd0 sr_mod
	#
	#
	# Now get ide-cd followed by ide-scsi loaded before the SCSI drivers
	pre-install sg        modprobe ide-scsi
	pre-install sr_mod    modprobe ide-scsi
	pre-install ide-scsi  modprobe ide-cd

Which also means you don't need to rerun lilo.
