That's Andrzej's idea, except he plans to "single step" real DMA from a
timer in order to spread the load out on the memory bus in time, if I
understood it.

It should come out ahead, but it seems we didn't really understand what
made simple DMA very slow, so it can be interesting whatever it does.
