The driver libIntelXvMC you are using opens DRM device by name
(drmOpen("i915", NULL)) which mostly works on linux, unless __linux__
isn't defined when building libdrm or /proc/dri/x/name doesn't exist (x
= 0,1,...). Anyway, the latest driver uses drmOpen("i915", busID)
instead of drmOpen("i915", NULL) which should work for you. You may
cherry pick commit ed267072db7c58ee16a458fd3dc24ce3a2d0061d from the
master branch of xf86_video_intel.
