"the person" does have a name.

Presumably you are using a 2.0 kernel.

The pcd driver in recent 2.1 kernels contains the standard CD-ROM ioctl
interface. Since it was implemented in 2.1 using the "uniform CD-ROM"
layer, I have not attempted to backport it to 2.0.

It is also possible to use the 'pg' driver to send ATAPI/SCSI commands
directly to the drive (the second option above, I think), however, the
author of cdparanoia will have to add support for that into the application
as pg does not use exactly the same interface as sg.
