Also, I noticed that X crashes appear even with the regular fbdev driver. Not sure what to do about this, might need to revert to 1.13.

Forward port for 1.13 was done by Marko Saukko, all I did was a tweak for 1.14 and corrected some paths here and there to match dss changes in more recent kernels, packaging etc. For kernel driver, I bluntly removed dependency to dss bits that appeared to be not upstreamed. I'm not sure at all it's done right, or if it's enough but at least it's been usable for 2D, and the few GLES tests I've done, did work.
So, we have usable driver, which is somewhat faster and more featurefull than the plain fbdev to use until someone comes up with a better one. Unfortunately I don't possess the skills to do that.

As far as the kernel goes, IIRC the whole vsync infrastructure never got fully upstreamed. That may mean that page flipping either won't work, or blows up as well

However, I've seen it cause (visual) trouble only with hildon-desktop for far.

whats going up?? update a bit abt achivments and still to be achived
Some goals to achieve / ideas / todo:
Cleanup all PKGBUILDS etc and put them to github so my absence can be compensated if necessary.
Package Xorg 1.13. Fbdev is broken apparently upstream, so this needs to be done to restore functionality. I will try to do that at some point if no one else is going to.
Update all neon builds.
In addition to neon builds of packages, provide also egl/gles2 builds (like Cairo, Enlightenment, etc)
Provide Weston with fbdev backend, and maybe something else too supporting framebuffer at compile time, like netsurf.
Sort Pulseaudio mess. Currently call audio works but anything else makes PA go 80% CPU time. Needs packaging.
SGX binaries need repackaging. This will probably end in me compiling mesa too.
New rootfs, especially since netctl is out.
Get people involved, I can't handle this currently by myself.
So, what I'm doing? I'm working on Awesome configuration for touchscreen devices, partially inspired by Hildon desktop. I've also been doing some theme work in that department, and otherwise.
Kernel side is completely in other hands, so we're going with the current 3.5 until upstream kernel is usable.
I guess that's about it. Comments, questions and suggestions are very welcome.

skry, are the android drivers for sgx in better shape? just wondering if maybe using them with libhybris would sort out some of your issues.

Edit:
If I understood correctly, this would require us to use Android kernel.

It seems the same issue is present for raspi folk, and even someone using chromebook, there's an issue opened at archlinuxarm issue tracker for it. So, nothing to do but wait for update that fixes it or revert to 1.13.
