--- Comment #11 from Brendan King <brendan.king at imgtec.com> ---
I'm pretty sure I've got this to work, by removing the following block of code
from function dri2_initialize_drm in platform_drm.c:

   /* Not supported yet */
   if (disp->Options.ForceSoftware)
      return EGL_FALSE;

and setting both GBM_ALWAYS_SOFTWARE=1 and LIBGL_ALWAYS_SOFTWARE=1 when running
Weston. IIRC, the first variable is needed for the compositor to use software
rendering, and the second for the other Weston processes.
