У меня: hda, hdb -- винты, hdc -- DVD-ROM, hdd -- CD-ROM, hde --
CD-RW. В любом случае что мешает руками настроить так, как
хочется?

Я уже не раз цитировал, но не вредно и ещё раз:
/usr/share/doc/cdrtools-2.0/cdrecord/README.ATAPI:
Even a CD-ROM cannot be used decently if you use only IDE
commands. Opening/closing the door, playing audio and similar
things cannot be done using vanilla IDE commands - you will need
SCSI commands to do this. But how do we do this with a drive that uses
an IDE interface?
The ATAPI standard describes method of sending SCSI commands
over IDE transport with some small limitations to the "real" SCSI
standard. SCSI commands are send via IDE transport using the 'ATA
packet' command. There is no SCSI emulation - ATAPI drives
include native SCSI command support. For this reason, sending
SCSI commands to ATAPI drives is the native method of supporting
ATAPI devices. Just imagine that IDE is one of many SCSI low level
transport mechanisms.

Никаких. cdspeed -s 8 -- и всё (специально для скептиков:
проверял лично, что регулировка работает -- копировал на винт
большой файл без команды cdspeed, затем с cdspeed -s 8, время
копирования при этом увеличилось более чем в два раза.
