For example, the Vivante 3D driver is a also another closed source drop from Marvell, but it is available in rpmdropbox (and I assume its licensing allows it so). Perhaps re-distributable (and being stored in public repository) is a too-strong word. The question really boils down to this: can the marvell-ipp be used in alternative distributions (that runs on OLPC) other than the official Fedora? And if yes, which whom (email address) can I ask to get them? 

Your speculation is reasonable, and your questions are understood.
However, we don't have the resources to answer these questions, there
are other more important things for us to do, sorry.

If you can't determine a useful answer from what you have available,
then I suggest you stick with software decoders.

That's why I would like to get the hardware to do the decoding, and the only way to do hardware decoding is through marvell-ipp - there is no alternative, unfortunately.
