Which pieces are you thinking about "putting together" ? Imho that alone
might be a monumental task which far exceeds a single GSoC.

If one splits Androids in two categories - "open-source drivers" and
"others", the former will be android-ia and android-x86. The latter of
which picks some (most?) things from android-ia.

Indeed it would. Note that most mesa drivers are supported to a level by
android-x86 - (cough llvm, radeonsi, tr1-nouveau). Although those pieces
are fairly android-distro agnostic.

Ideally Androids will use upstream for drivers (mesa, drm, drm_gralloc,
hwcomposer, kernel?) and send back patches. For all we care they can do
whatever they want with the rest of the stack.

P.S. The whole android-x86 "obsession" is because it's the only one I
have experience with, rather than it being better or whatever.
