It probably doesn't matter much wrt. the general issue here, but note that the hardware in question doesn't have fragment shaders either.
Ya, João won't see that issue because of that.
Well, sort of. In principle the drawable only has to be large enough to fit the area that's being copied, not the entire surface. I think in most cases that's enough in practice, though even if it isn't you could in principle do the copy in multiple passes.
That's possible for blits, but I think it's overkill. If you don't have FBOs some things aren't going to work.
For the shadow ddraw frontbuffer moving the shadow frontbuffer into wined3d would help. For all other cases I'd say get a card/driver with FBOs if you want to run a game that does complicated offscreen operations.
(Either way, all this has no relation to the original issue in this bug.)
