I will try to have a look later; unfortunately the code in apt-cdrom isn't
really actively maintained by anyone…

"acquire::cdrom::autodetect=0" should disable udev usage.
Use "-o acquire::cdrom::mount=/path/to/media" (or -d) to specify
the directory to look for the disk and call apt-cdrom with
"-o APT::CDROM::NoMount=1" (or -m) to prevent it from trying to
mount/unmount a disc at that location.

We have a small testcase covering some bits of apt-cdrom which uses
all this, so have a look if you want to see it in "action":

(and the code "creating" a "CD-ROM" for the test)
