Okay, I've tested it out from scratch and mounted an old encrypted test file
with an ascii password hashed with ripemd160:

tar jxf linux-2.4.22.tar.bz2
wget http://www.kernel.org/pub/linux/kernel/people/hvr/testing/patch-aes-asm-2.4.22.0

tar zxf hashalot-0.1.0.tar.gz
cd hashalot-0.1.0
./configure
make
make install

<AFTER REBOOT>

hashalot ripemd160 | losetup -p0 -e aes-cbc-256 /dev/loop3 test
Enter passphrase: 
mount /dev/loop3 /mnt

Can I do this in one step yet? (I've just run out of time before
I have to start supper) I'd rather just mount in one step like I
did before.
