Will ATI's lower-end cards also support Eyefinity?

[VirtualLarry]

Just wondering. Obviously, their flagship 5870 and probably 5850 will, but will lower-end cards also support it? It might be a nice cheap way to deck out a multi-display system if they do. I dunno though, wouldn't it require a double-wide card to have all of those outputs on it? I don't know if the lower-end cards are going to be double-wide. Somehow I doubt it.
