i don't currently have a machine to test this, if you still have one handy,
could you check a few things?

the LTSP plugin that handles the CD mounting is rather stupid, assuming that
/cdrom is the only location for a valid CD-ROM. 

what links are present? /media/cdrom, /media/cdrom0, /media/cdrom1 ? are they
mounted in /target/media/ ? is there a symlink from /target/cdrom and/or
/target/cdrom0 ? 

we could try and look at a few more locations to make make the code
incrementally smarter, but this will of course fail if debian-installer changes
the mount location(s).

ideally, we could look into the debian-installer's debconf db and ask a few
questions about the proper location of the install media, if we knew which
questions to even ask. last time i looked, it was a confounding maze of
questions; perhaps it has improved more recently.

live well,
