(git master 73b46136b0ba20f7f84abdadad895111a4c37166)

I've built Mesa with the following configuration:

./autogen.sh --enable-gles2 --disable-glx --with-dri-drivers=
--enable-gallium-egl --with-egl-platforms=drm --with-gallium-drivers=i915

With this configuration, both a DRI driver and a Gallium driver get built,
despite the --with-dri-drivers= configure option (bug or intended?).

Then I've built the 'es2gears' demo as follows:

gcc -g -O0 -DMESA_EGL_NO_X11_HEADERS -o es2gears es2gears.c
../eglut/eglut_screen.c ../eglut/eglut.c -I../eglut -lGLESv2 -lEGL -lm

When I tried to run it on an IBM T60 notebook (Debian testing), at first bug
75335 triggered. Now that this bug has been resolved, the following error
occured:

-----
EGL_VERSION = 1.4 (DRI2)
EGLUT: failed to choose a config
-----

When I deleted the DRI driver, the following error occured:

-----
gbm: failed to open any driver (search paths /usr/local/lib/dri)failed to load
driver: i915
gbm: failed to open any driver (search paths /usr/local/lib/dri)failed to load
driver: i915
gbm: failed to open any driver (search paths /usr/local/lib/dri)failed to load
driver: i915
EGLUT: failed to initialize EGL display
-----

Apparently, the Gallium driver was not usable, too. Since bug 75335 got
triggered by the missing DRM pipe loader, I tried to enable it with the
following modification of configure.ac:

-----
index ba158e8..feb025f 100644
--- a/configure.ac
+++ b/configure.ac
@@ -1748,6 +1748,7 @@ if test "x$with_gallium_drivers" != x; then
         xi915)

                 GALLIUM_DRIVERS_DIRS="$GALLIUM_DRIVERS_DIRS llvmpipe"
-----

With that, the demo finally worked:

-----
EGL_VERSION = 1.4 (Gallium)
Found 6 modes:
  0: 1400 x 1050
  1: 1400 x 1050
  2: 1280 x 1024
  3: 1024 x 768
  4: 800 x 600
  5: 640 x 480
Will use screen size: 1400 x 1050
vertex shader info: 
fragment shader info: 
info: 
724 frames in 5.0 seconds = 144.713 FPS
-----

So it seems that the DRM pipe loader should get enabled by default for the
i915/DRM Gallium configuration, but I'm not sure if the modification I made
would break some other configuration.
