What about kernel add-on packages
that would insert the pseudo-driver shim
and the apps to use it?
If you mean, for instance, can I put an ISO image on my HD and mount it, then
it's built in to the Kernel:
mount -t iso9660 -o loop,ro <path to image> <mount point>

no, that is not what I meant. I really mean a cd/dvd/optical media hardware
and not the FS support of iso9660.
I read some blogs about cdemu, which is not
available in the fedora repos.
Yes, although the utility of that is questionable. No emulator will let you do
things like a proper rip of a CD, because the fancy subtrack and odd preburn
areas and such aren't in your image. And if you are debugging optical media
drivers, I doubt any emulation will be a bizarre as burner firmware.
You can get a better emulation by using kvm, starting qemu-kvm with the -cdrom
option, but what you need to emulate is the optical media device, as well as the
media itself, and the accuracy of emulation is dubious.
