I realized after I wrote this email that WIN_WRITEDMA should be the
right command invoked. I added some printf, nope, it's never called.
WIN_READ on the contrary is always called. I'm poking around the
command now to make it like it's DMA'ed.

I wrote my previous email too soon, without experimenting much. I'll be
more careful.
