At first glance this seems to be caused by a problem in the tool used to create the binary packages on Arch Linux [1]. For whatever reason I had never realized that the Openchrome 2DDX driver does need root permissions and hence searched in the wrong directions. X version 1.20.11 was nothing but a red herring as it happened to be the first binary package affected by the packaging bug. Now running the X server with root permissions is actually quite unfortunate these days. May I assume that this is only due to the lack of DMS/KMS and no longer needed when these are in action? On a side note a framebuffer driver certainly wasn't involved. All those hardware specific ones including viafb as well as uvesafb were removed from the Arch Linux kernels long ago, see e.g. [2]. vesafb is compiled into the kernels but was disabled by command line option vga=normal all the time.
