I plan to do it for myself. I code in C, though, not C++. I can submit it
to you, but it is up to you to accept it or not.
Besides, have to wait from AMD to support my Ubuntu 13.10 or 14.04 coming
up. I am also interested in their new PVA
(crossfire) architecture.

the rainbow tables are built with A51 encryption in them?
If that is the case, there is a project openrainbow tables, that maintains
them and maybe takes care of it.
