I know this thread is very old, but it is definitely not obsolete. I am testing compatibility of the UX with the later Ubuntu 14.04 lts, and with this new patch, it works even with this latest long term release version!
So far the only issues I can see so far in the latest Ubuntu 14.04 is the intel GPU drivers seems to malfunction when an external VGA monitor is connected. So as long as you use only the small 4.5" built in display, the GPU will work fine! So far, I have managed to undervolt, re profile the fan speeds, and calibrate the touch screen.
