No progress:
$ eject /dev/sr0
eject: unable to find or open device for: `/dev/sr0'
$ eject /dev/sr1
eject: unable to find or open device for: `/dev/sr1'

Check /var/log/messages or run /bin/dmesg right after booting. If you
have a recent standard kernel, it should detect the cdrom drive and load
a driver for it.
Mine looks like this:
Aug 31 11:03:16 whitewave kernel: scsi 5:0:0:0: CD-ROM PLEXTOR DVDR PX-712A
1.03 PQ: 0 ANSI: 5
Aug 31 11:03:17 whitewave kernel: sr0: scsi3-mmc drive: 125x/125x writer cd/rw xa/form2
cdda tray
Aug 31 11:03:17 whitewave kernel: Uniform CD-ROM driver Revision: 3.20
There may be other unrelated lines between these lines in the messages
file. Once you've verified that the kernel sees your drive and is
loading a driver, you can create inode entry in /dev with something like
this:
cd /dev
./MAKEDEV sr
Then you can create a symlink to /dev/cdrom
ln -s ./sr0 cdrom
Unless your system is screwed up in some other way, my sense is that
this should work. Otherwise you can use mknod to create the device.
