PLEASE DON'T DO THIS!!!! How would you then handle partitioned cdroms?

I know, you say to yourself "Is there such a thing as a partitioned CD?"
Well, there is. Every Macintosh CD includes a partition table. In >90%
of the cases there is a single partition, but this in not always the case.
One example is a CD with one year worth of a magazines "supplement"
floppies. I know this isn't the best use of CD technology but it exists.

I know that the last time I checked Linux didn't even bother to check for
a partition table on an IDE cdrom. However, I wan't to see that change
when the various PPC ports start getting integrated into the main kernel.
Mapping cdrom changer slots to partitions would make this impossible.
