I guess I stand educated, I've never had a problem with that, but
until I learned about the hdX=ide-scsi trick, I used to use modules and
unload the ide-cd when I wanted SCSI. Since then I've not had a problem,
but obviously I haven't used every kernel, and I usually run the Alan
Cox patches which often ward off evil.

I'll keep this in mind as a possible point of interaction, but I'm
happy to say I've never had any problems of this nature, and I almost
always have had both an ATAPI reader with ide-cd on systems with a
burner, because until recently burners were unpleasantly slow for
day-to-day reading.
Thanks for the tip.
