/dev/cdrom is usually a symbolic link to your real CD-ROM
drive.  'ls -l /dev/cdrom' should show it linked to something
like /dev/scd0  (Was yours a link to an early CD-ROM, not CD-RW
drive?)

Mine looks like:

hdc: attached ide-scsi driver.
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
  Vendor: CDWRITER  Model: IDE1610           Rev: 0.21
  Type:   CD-ROM                             ANSI SCSI revision: 02

With a modular kernel, try 'lsmod' and looking for modules like:
ide-scsi               12016   0 
scsi_mod              106584   3  [sg sr_mod ide-scsi]
ide-cd                 35424   0 
cdrom                  33216   0  [sr_mod ide-cd]
