There is no DMA between the host CPU and anything.

In theory, you could use the frame buffer RAM of a PCI video card as system memory, as long as you weren't using it for video too. You'd have to write code to initialize the RAM controller on the card and AddMem the RAM to let the system know it was there.

Not really practical, but it could be done.
