But since my boot drive is an IDE, it can not be a module. So if I boot
with the DVD as IDE, but want it to be temporarily SCSI, I can just load
the IDE-SCSI module and then unload it? I thought I had tried that, but
the IDE wouldn't let go of the drive.

No, I don't need DMA for the CD to CD copy, but I need it on the DVD
player to be able to play DVDS at greater than 1 frame per second.
