problem with cryptoapi-2.4.7.0 mounting crypto fs

[Davide Giunchi <gdavide@mclink.it>]

Hi all.
I'm using a Debian unstable (upgraded to 3 weeks ago) with kernel 2.4.7, i've 
installed cryptoapi and patched+installed util-linux (someone tell me that 
util-linux included in debian unstable are already patched... but i've 
recompiled it anyway).
Now i try to create and use a crypto fs:

# modproble cryptoloop 
# dd if=/dev/zero of=/file bs=1k count=100
# losetup -e blowfish /dev/loop0 /file
 i select 256 bit and a passhprase
# mkfs -t ext2 /dev/loop0 100
in the next step i get the error
# mount -t ext2 /dev/loop0 /crypto/
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
or too many mounted file systems

so when i try to mount the fs it doen't prompt for a password and i cannot 
mount the filesystem.
What can i do?

Regards.
Davide.
