How do you mount Debian in openSUSE? Maybe you can wright a script for your autostart when logging in or maybe rclocal. Documentation seams to be skimpy on the and the only thing I could find was an FAQ that said to mount with a loop0 when doing a backup.

Description: configures encrypted block devices
Cryptsetup provides a command-line interface for configuring encrypted devices. This is done using the Linux kernel device mapper target dm-crypt. This
version of cryptsetup has integrated support for LUKS.
cryptsetup is backwards compatible with the on-disk format of cryptoloop, but also supports more secure formats. This package includes support for
automatically configuring encrypted devices at boot time via the config file /etc/crypttab. Additional features are cryptoroot support through
initramfs-tools and several supported ways to read a passphrase or key.
That's all I could find and you may have all ready seen this stuff.
