[PATCH] interlaced packed pixels

[Geert Uytterhoeven]

	Hi,

I'd like to introduce a new frame buffer type to accommodate packed pixel frame
buffers that store the even and odd fields separately. This is typically used
in graphics hardware for TV output (e.g. set-top boxes).

The patch applies to both 2.4.x and 2.5.x.

Any comments?
