i used an encrypted partition using twofish-256 under gentoo with kernel
and 2.6.9. Today i installed SuSE 9.2 and would like to take over my data
from that partition/harddisk. But that failed with:

requested cipher or key length (256 bits) not supported by kernel

after a long warning message:

Passwords shorter than 20 characters are considered too short and insecure.
Use of rmd160 password hash permits use of such short passwords for
compatibility with other systems that do not enforce minimum length.
SuSE has introduced a patch which also permits short passwords with
a minimal length of 8 characters for all other hashes.
Hopefully this message is annoying enough that you discontinue using such
short passwords.

I thought, ok lets use rmd160:
# losetup -e twofish256 -H rmd160 /dev/loop0 /dev/hdb1
but that did not help at all

The twofish-module loads fine into the running kernel.

Something i missed?
