Sorry, what a stupid mistake I made. Corrected the diagnosis is:

# update-initramfs -u
update-initramfs: Generating /boot/initrd.img-2.6.32-5-amd64
cryptsetup: WARNING: invalid line in /etc/crypttab -  (target=vg-md1dm0, 
extraopts=rootdev,lvm=vg--md1dm0-slash, @=vg-md1dm0 
rootdev,lvm=vg--md1dm0-slash)
cryptsetup: WARNING: invalid line in /etc/crypttab -  (target=vg-md1dm0, 
extraopts=lvm=vg--md1dm0-swap, @=vg-md1dm0 lvm=vg--md1dm0-swap)

I have no idea why / and swap lvs are affected - I had assumed this 
referred to md1_crypt and md2_crypt, but no.

Yes.

Do the crypto

No.

What about LVM?

# cryptsetup luksOpen /dev/md1 vg-md1dm0
[System asks for Passphrase]
# <Passphrase>
[System silently accepts passphrase]
# lvm
lvm> vgchange -ay vg-md1dm0
[System reports the logical columes as active]
lvm> exit
# exit  [from rescue shell]

Then the normal booting resumes, asking the question for md1's 
passphrase, and when md1 has been unlocked, the same happens for md2, 
and then the system completes the boot process in the proper way.

That's what I think (manual creation). And without specifying the vg I 
receive the error message  that no volume groups are found
