Just some thoughts: What happens if you
* try `/dev/disk/by-uuid/' instead of `UUID='
* try the raw devices (presumably /dev/md1 and /dev/md2)
* try the symlinks to the devices (presumably /dev/md/1 and /dev/md/2)
(note that you *might* need the new mdadm version for that to work)
Hm. All three variants yielded the same result:
# update-initramfs -u
update-initramfs: Generating /boot/initrd.img-2.6.32-5-amd64
cryptsetup: WARNING: invalid line in /etc/crypttab -

Then I followed this previously mentioned error message:

Perhaps this is the source of confusion? Identical UUIDs for the
encrypted RAID1 pv and the vg that emerges when the pv has been unlocked
with cryptsetup? This is the configuration on the running system on
which md1_crypt and the vg had been unlocked and started manually. Do I
have to remove one symlink, either to dm-0 or to dm-11 in order to
create a functioning initramdisk? I had to unlock md1_crypt twice, once
from within busybox and once after exiting lvm and busybox.
What else could I try, or what further info from my system might be helpful?
