With the ov511 driver, that would actually eliminate an RGB-to-YUV *and* 
a YUV-to-RGB conversion. It won't save any USB bandwidth since the 
native format is already YUV420,  but it will save a LOT of CPU cycles.

In other words, there really is a strong technical reason why V4L 
drivers shouldn't convert between standard formats. IMHO, one of the 2.5 
goals should be to (at minimum) eliminate the conversion code that does 
YUV<->RGB from the kernel. I promise to do my part :)
