I have source to a mplayer which uses the MFC/PP as the video codec for the 
four video encodings it supports.  A hd video with MFC decode utilizes ~30% of 
the 6410 and without the HW assist utilizes all the CPU and still drops 
frames.  This is all within Xwin using the fbdev.

This MFC/PP driver pair is useful to users now.  I am sorry they are not 
good enough for the next-s3c.
