+1 on Ubuntu 13.04 with kernel 3.8! Upto Ubuntu 11.04 it worked as expected. If this is a regression bug between 3.2.0.41.49 and 3.2.0.43.51 it would be recommended to report it upstream on kernel.org ...

My symptoms:

No matter if I take /media/cdrom or /cdrom or /dev/sdb or /dev/sdb1:
$ sudo hdparm -E 24 /cdrom
...
setting cd/dvd speed to 24
 SET_STREAMING/CDROM_SELECT_SPEED both failed: Inapropriate ioctl for device

My known alternative does not work either:
$ sudo eject -vx 24
...
eject: CD-ROM select speed command failed: Invalid argument
