as root, try chmod a-rwx /etc/modules.conf, and then
chmod +rw /etc/modules.conf

That should allow you to modify it as root. And to get scsi emulation,
find which cd you want to be emulated (ie hdb or hdc), then edit
lilo.conf to say something like this:

image=/boot/vmlinuz
        label="linux"
        root=/dev/hdc5
        initrd=/boot/initrd.img
        append="quiet devfs=mount hdd=ide-scsi hdb=ide-scsi acpi=off" <-- add [CD 
ROM]=ide-scsi
        vga=794
        read-only

Then, edit /etc/fstab and make it look like this (only the cdrom lines, there are many 
more lines):

none /mnt/cdrom supermount 
dev=/dev/scd0,fs=auto,ro,--,unhide,iocharset=iso8859-1,codepage=850,umask=0 0 0
none /mnt/cdrom2 supermount 
dev=/dev/scd1,fs=auto,ro,--,iocharset=iso8859-1,codepage=850,umask=0 0 0

You need to change dev=/dev/[CD ROM] to dev=/dev/scd0.

HTH,
