first, thanks for the bugreport. the reason for change of bahaviour is a
line in /usr/share/initramfs/scripts/local-top/cryptroot that sets $ROOT
to $NEWROOT in /conf/params.conf in the initramfs:

302:			if [ "$cryptrootdev" = "yes" ]; then
303:				# required for lilo to find the root device
304:				echo "ROOT=$NEWROOT" >> /conf/param.conf
305:			fi

commenting out these lines and regenerating the initramfs
(update-initramfs -u) afterwards should fix it. could you verify that?

unfortunately these lines are required in order to support setups with
cryptroot on lvm and lilo as bootloader. thus i don't know what to do
about that bug yet. will have to do further investigation and testing
with lilo as bootloader first.

greetings,
 jonas
