See, you not only have to be a good coder to create a system like Linux,
you have to be a sneaky bastard too ;-)

God knows I'm not an authority on this, but I believe the answer to this is no; you need to do DMA from VINO to memory, then memory to XMAP9 through REX3.
Please tell me if I'm wrong.

As far as I know, you have to do it through memory.
To elaborate: I believe you can program the DMA controller to copy from VINO to the REX3 (read: from a fixed address to a fixed address), but I doubt the data formats are compatible. Ie, you'll be dumping garbage to the REX3 registers.
