Good idea. It could be the the 'false satoshi' is actually an false bit. I've tried dropping the first bit of the data but no success.
I can at least verify that the padding does not contain a vigenere cipher with either 'rabbit', 'axiom', 'cipher' or 'white' as keyword with either 5, 6, 7 or 8-length bytes.
If anyone else wants to play with it here is the binary data hidden in the padding:

The binary data does not include the spaces that are part of the message. Tabs=1 spaces=0.
