DSS2 is still under active development.  This setting makes user
support easier since boot logs contain needed debug info.

I'm not sure exactly what you are suggesting.  The current setup is
tailored to make user support easier.

If someone wants to use the 4.3" LCD display option, you tell them to
simply type:

setenv defaultdisplay=lcd43
saveenv

Or if they want to change the DVI resolution to 640 x 480:

dvimode=640x480MR-16 at 60
saveenv

Perhaps I'm jut not understanding your suggestion.  Could you give more detail?
