As requested on IRC, I tested this quick hack to work around broken code
that identifies CD drives (my drive being /dev/hdb):

With this, the CD isn’t locked anymore and I can insert disks into it,
but it is still not usable by nautilus, which behaves as if no media was
introduced in the drive. After that my kernel logs are full of scary
error messages:
