you're missing the cryptoloop module... the glue between loop.c's filter
API, and cryptoapi ...

cryptoloop is a tarball of its own,
http://www.kernel.org/pub/linux/kernel/crypto/v2.4/testing/cryptoloop-0.0.1-pre1.tar.bz2

but you may want to (in case you have 2.4.20) use directly
http://www.kernel.org/pub/linux/kernel/crypto/v2.4/testing/patch-int-2.4.20.1.bz2
and
http://www.kernel.org/pub/linux/kernel/crypto/v2.4/testing/loop-jari-2.4.20.0.patch

which contains the latest versions of crypto{api,loop} in an easy to use
patchset and is known to work well;
