How do I use this later uboot with the old F19 image?  What files do I 
copy from a F21 SDcard to the F19 SD card?

Of course, I actually LIKE that the uboot that comes with F19 has 
working video, whereas F21 with the more uptodate uboot does not. 
Sometimes I want a boot that I can use a keyboard/mouse on a GUI with.

I am assuming that the uboot in F21 is the most current for Cubietruck.  
I have the git instructions for building my own Cubieboard2 uboot from 
your repository for F21.  For F19 on the C2, I use what you provide.
