Encrypted LVM partitions

Does anybody here have any experience with encrypted lvm partitions
mounted at system startup? I'm running SUSE 10.1 (inside of VMware) and
I want to have an entirely encrypted system where *every* partition is
encrypted. I am most of the way there but can't seem to get to the next
step.

Here's what I have:

/dev/sdb2 -> cryptsetup-luks -> /dev/mapper/root
/dev/sda2 -> cryptsetup-luks -> /dev/mapper/swap
/dev/mapper/system-home -> cryptsetup-luks -> /dev/mapper/home
/dev/mapper/system-shared -> cryptsetup-luks -> /dev/mapper/shared

I used the instructions on the OpenSUSE site to get the encrypted root
and swap partitions to work using a modified 'mkinitrd'.

http://en.opensuse.org/Encrypted_Root_File_System_with_SUSE_HOWTO

That part is working like a charm. When I boot, I am presented with an
opportunity to enter my password. On doing so, it decrypts my root and
swap partitions, mounts them, and continues.

Once booted, I can map my LVM partitions to the cryptsetup ones
(system-home to home and system-shared to shared). I can then mount the
decrypted mappings (home and shared) to the proper directories and
everything works great.

The problem comes when I try to mount those LVM partitions during the
boot process. When it comes time to mount them, I am presented with a
password prompt... but no password works. I am nearly certain that it's
because the /dev/mapper/system-{home|shared} LVM devices don't yet exist
in the initrd process.

But how? I'm missing some crucial step, it seems, in figuring out how
to get this all to work.

Any clues?
