Ric, grab the cdwriter howto and extract the test script and modify/run it and see what it shows. I still think you are missing some modules - I believe not all not all the ones normally loaded are ide specific, but sit on top of the scsi layer (which may be real scsi or ide-scsi. The test script should find and load the modules as needed.
