No problems expected with XwinNMR, but it will not solve the CD-ROM
detection. You have to fix the kernel boot parameter in /etc/grub.conf
or /etc/lilo.conf (depending with boot loader is used)

In grub.conf:
    title Red Hat Linux (2.4.20-20.7)
            root (hd0,0)
            kernel /vmlinuz-2.4.20-20.7 ro root=/dev/hda2 hdd=ide-scsi
the value "hddd=ide-scsi" must point to the correct device of the ATAPI
cdrom. Try the command "du /proc/ide" and you will get a list of attached
devices on the IDE bus.
e.g.:
    0 /proc/ide/ide1/hdc
    0 /proc/ide/ide1
    0 /proc/ide/ide0/hda
    0 /proc/ide/ide0
    0 /proc/ide
The command

cat /proc/ide/ide?/hd?/model

will show where your CR/RW device is connected. In my example:
gsc@viola(11)$ cat /proc/ide/ide1/hdc/model
HP CD-Writer cd16b

the 2.4.20-20.7 kernel is the newer one with the latest bug/security fixes

No, only glibc version specific.
