No, I think you are missing my point.  ATAPI CD drives (DVD, CDRW, 
whatever, that use an IDE controller) can be controlled by either the 
IDE driver or the SCSI driver.  If you want to write to a CD, you have 
to use the SCSI driver because SCSI supports features that IDE doesn't 
(and Joerg Schilling used it in cdrecord which has little competition).

If you want to read from an ATAPI drive, you can use either the IDE 
drivers or the SCSI drivers.  If IDE works better for you, use those. 
If your drivers are modules, it shouldn't be hard to switch them out. 
Probably your IDE driver loads first.  Probably you have settings 
(modules.conf) to tell it not to grab the burner.  Probably you'll have 
to adjust that.  Once you understand it, write a script to make it easy.
