Oh, thanks. Now I understand. From the product brief 
http://www.erd.epson.com/vdc/html/contents/S1D13742.htm and from kernel 
sources I wrongly guessed that the conversion is done on the fly (per 
each update) when moving data from main memory to videoram. But as it is 
simple DMA it looks like nonsense. Yet it is interesting that the chip 
must do same operation when moving data on the fly from its internal 
video memory (if setup as YUV) to LCD hardware in RGB. Why this is 
possible and the first one not?

But anyway we could still hack it and change the format at least at 
fullscreen for video playback. This should be possible with some dirty 
tricks, correct?
