There's also overlap:
C) Do the improvements in the way that allows using the N800 software
on N770 (maybe with recompile) and vice verse.
And the question on which level the improvements are done.
If pixeldoubled RandR gets into N800 Xserver, somebody could port it
back to N770. How this and the proposed N770 hack are used through
the SDL might not be same, so it makes sense to discuss both.
