It's kernel changes. In 2.4 and previous, the only way to send generic
userland commands to ATAPI devices was to get the kernel to make them
appear as SCSI devices (using ide-scsi). With kernel 2.6, ide-scsi is
deprecated; ATAPI devices are expected to handle the SG_IO commands
directly through the /dev/hd interface. The commands sent to the drive
are the same in the end, but the kernel no longer invents the details
of a SCSI bus for cdrecord -scanbus to look at.
