Is this really true?
Didn't find a datasheet explaining the Client-side requirements, when
AES-256-encrypting PDF documencs with LCRM.
In my lab it seems, as if Reader-9 can open those documents fine, while Reader-8 fails decrypting.

Acrobat/Reader 9 were the first version to incorporate AES-256 code, so if you want to remain backwards compatible with Reader 7 or 8 you need to continue to use AES-128. I believe this is documented in the help for the section that describes how policy edit works.

Only Acrobat\Reader 9.x support the decryption of Rights Managed documents encrypted with a 256 bit key.
