udev mounts the old /dev on /etc/udev/.dev before it mounts its own
temporary filesystem over /dev. If /dev/Foo exists before udev
starts, then it will continue to exist as /etc/udev/.dev/Foo.
After udev starts, it controls what exists in /dev. udev begins by
copying all entries from the existing /dev. Then it reads all the
rules specified in /etc/udev/rules.d and creates the requested nodes
for devices it finds in /sys. (/sys is a on-the-fly view into the
kernel, similar to /proc)
The question, then, is twofold :
1) does your CD drive present itself via /sys?
(if you use the 'ide-cd' driver then it does)
2) Is udev on your system configured to create a device node for
that drive, and if so by what name?
To track this down, first see what files are symlinked into
/etc/udev/rules.d. See if those files have any rules for IDE disks
(most likely it does) and see what name it gives to them. Some of the
provided rules files use names like 'hda', etc, and another uses names
like ide/host0/bus0/target0/lun0/disc. Second, look in
/var/log/syslog to find the information udev logs as it creates nodes.
Does /dev/ide/host0/bus0/target1/lun0/cd exist by any chance?
Does /dev/cdroms exist?
