There *used* to be problems with some controllers, most notoriously the
CMD640. For more details, see Documentation/cdrom/ide-cd and

The CMD640 is now obsolete.

two devices on the same channel *if* they are both going to be heavily
used at the same time.

If they are used for different OSes, that sounds fine.
