The BT8x8 cards can generate such frames, and mpeg encoding starts off by generating YUV from RGB (and it is a major CPU killer - witness how much CPU the Xv extension saves you when playing a movie - the CPU no longer has to do YUV -> RGB) And, uhh, no, I have no patches :) > I'll post a link when I get there.
