For reference, that would be p512 of
http://www.amd.com/files/connectivitysolutions/geode/geode_lx/33234E_LX_databook.pdf
and chapter 18 of Applied Cryptography, "ONE-WAY HASH FUNCTIONS USING
SYMMETRIC BLOCK ALGORITHMS".

As a stopgap, using only SHA-512 (and leaving off the whirlpool hash)
will more than double our authentication speed.
