The speed of the optical drive is set separately for CD-ROM and DVD, and is reset at reboot and resume from suspend.

  • CD-ROM: use
hdparm -E num


eject -x num
  • DVD: use
speedcontrol -x num

(sourcecode here).

For recent ThinkPad models running Linux kernels older than 2.6.15, this may require the libata pass-through patch.
