Has anyone been able to set up a loopback encrypted filesystem?

I read Loopback-Encrypted-Filesystem-HOWTO. It refers to kernel
patches at ftp.kerneli.org/pub/kerneli -- there is a crypto
dierctory there, but it is empty. Same situation at ftp.kernel.org.

Also, SuSE seems to have alerady done some of the steps outlined in
the HOWTO. For example, without doing anything special, XOR works:

        # losetup -e XOR /dev/loop7 /etc/cryptfile
        Password: mypassword
        # mkfs -t ext2 /dev/loop7
        # mount -t ext2 /dev/loop7 /crypt
        # cd /crypt
        # echo "Hello World" > /crypt/hello
        # ls /crypt
        .  ..  hello  lost+found

DES almost works (but the HOWTO says DES isn't supposed to work
anyway):

        # losetup -e DES /dev/loop7 /etc/cryptfile
        Password: mypassword
        Init (up to 16 hex digits): 12345678990abcdef
        ioctl: LOOP_SET_STATUS: Invalid argument

Any other algorithms I try fail even sooner:

        # losetup -e twofish /dev/loop7 /etc/cryptfile
        Unsupported encryption type twofish

Looks like all I really need to do is compile some algorithms as
modules.
