Prbl: Forgot to provide seed when crypting /

Hi,

I'm stuck with an unusable disk :
I followed loop-aes.readme and Gentoo's
http://forums.gentoo.org/viewtopic.php?t=108162&postdays=0&postorder=asc&start=0 instructions on building
encrypted root partition.

However, when modifying buil-initrd.sh I uncommented the SEED and ITERATION
options (can't remember exact names) and broke cardinal rule by not writing
seed down on paper ;-(

I then followed the remaining instructions to the letter. Immediately after
crypting my root from Knoppix, I remembered that I didn't provide any seed.

2 questions :
-how can I decrypt my root partition ? 
 dd if=/dev/hda5 bs=64k | /mnt/aespipe -d -K /mnt/rootkey.gpg -G / | \
     of=/dev/hda5 bs=64k conv=notrunc
-If providing seed in initrd what command should I have used ?
 dd if=/dev/hda5 bs=64k | /mnt/aespipe -e AES256 -H SHA512 -K
/mnt/rootkey.gpg -G / | \
     of=/dev/hda5 bs=64k conv=notrunc
