Why not the Nx speed (that is, 176 kb/sec)? That's more user-frendly. Note also that cdrom_device_info.speed is in this unit. Moreover, note "CDC_SELECT_SPEED& can select speed, in units of $\sim$150\,kB/s\cr" (sorry about the raw tex).
I don't know which, but it seems that units of 176 kb/sec or 150 kb/sec would be best. BTW - Is it just me, or is there no function to kill the motor on the CDROM? IMHO, there should also be a behavior flag CDO_AUTO_MOTOR to kill the motor on device close (if opened for data).
