fbdev-driver you have is not compiled for Xorg 1.14, try pacman -Syu and if there is no updated version, you need to pass -ignoreABI to Xorg, chances are it may even work.

For the SGX variant, you need to start/enable powervr service first, there are modules and firmware to be loaded. Cant remember if I compiled it for 1.14 or not.
