We stopped trying to load the Intel X driver and just use fbdev instead on your hardware. :) You should be able to degrade your experience (in some ways, gaining features in others) back to Lucid by manually selecting the Intel driver in xorg.conf (see https://wiki.ubuntu.com/X/Bugs/Mavericki8xxStatus for instructions). If that still doesn't get you back to Lucid's behaviour, yay! Magical kernel fairies have come in and fixed everything!
