Thanks Richard, I seem to have solved my problem a little while ago,
and here's how I did it:
1) I edited the /etc/conf.modules file and took out the 2 lines
dealing with SCSI emulation:
alias scsi_hostadapter ide-scsi
...
post-install supermount modprobe scsi_hostadapter
...
2) I then edited my /etc/lilo.conf file and took out the line that
also dealt with SCSI emulation:
...
image=/boot/vmlinuz
label=linux
root=/dev/hda11
append="hdc=ide-scsi"-- Took this line out!
read-only
3) I ran lilo -v (as root) to update the boot record
4) When I rebooted, some auto-hardware detection program complained
about me disabling the Yamaha CR4416E, so I chose to have it keep
the existing configuration, but not warn me in the future about it
being disabled (or something to that effect!)
Now I am able to mount either of my CDROM drives at will from the KDE
Desktop!
What still bothers me, however, is that I am now getting those pesky
messages that I got in RedHAt 6.1 in the /var/log/messages file:

Anybody got any clues on what's going on wrong here? Is this drive still too new
for Linux drivers to have caught up?
Thanks,
Tom

I had a similar problem. First make sure you can mount the CD-RW manually. I
think the installer is smart enough to determine the drive is CD-RW, so it
sets up the SCSI emulation for you. It just doesn't change fstab to reflect
this. Try (assuming you want to mount it on /mnt/cdrom2):
mount -t iso9660 /dev/scd0 /mnt/cdrom2
You may have unmount /mnt/cdrom2 first. If this works, change the following
line (again assuming fstab is trying to mount your CD-RW on
/mnt/cdrom2/):
mnt/cdrom2 /mnt/cdrom2 supermount fs=iso9660,dev=/dev/cdrom2 0 0
to:
/mnt/cdrom2 /mnt/cdrom2 supermount fs=iso9660,dev=/dev/scd0 0 0
You are changing the "dev=" portion to point at "/dev/scd0".
Hope this helps.
