Actually, 128 bit is a ver. 5.0 requirement.  I'm using this exact setup in
my app (iText w/ FOP for encryption), and we are requiring all users to have
AcroReader 5.0 for 128 bit encryption.  Also, if you encrypt at 128 bit, and
then check the encryptions properties of the doc in Reader, you'll see
strength 128 and next to it, 5.0 in parenthesis.
