TIA,
Try dmesg | grep sr0 this should give you a line describing the first scsi device with the speed(s) in it use sr1 if it is the second cdrom in the system. You could also use scsi to get every line with scsi in it from the boot messages also I have found it helpful to look at the drive it usually has the speed(s) on the tray.
