Ok, I found some time while watching a boring movie. It doesn't work, I'm
afraid.

Some notes to clarify things a bit, just in case.
The dvd contains a reiserfs image, encrypted.
cer@nimrodel:~> file -s /dev/hdc
/dev/hdc: LUKS encrypted file, ver 1 [aes, cbc-essiv:sha256, sha1] UUID:
bcfe5715-c092-4fea-b2dc-7951cb2
The image was first generated as a HD filesystem on a file which can be
normally mounted via "/etc/init.d/boot.crypto start IMAGEFILE". Data is copied
there, then umounted ("boot.crypto stop IMAGEFILE"), then the IMAGEFILE is
burned normally to the dvd. The journal should thus not have anything pending.
It looks as if the system tries to activate the journal, sees it can't write to
it, and continues happily. The doubt is what would happen on a hard disk
partition mounted RO: think of somebody doing a forensic analysis, what would
happens if the kernel writes to it...
