I took some more time to look into it and by doing:
1) add "i915g" to GALLIUM_DRIVERS in debian/rules
2) add "build/dri/${DEB_HOST_MULTIARCH}/gallium/i915_dri.so
usr/lib/${DEB_HOST_MULTIARCH}/dri/gallium" to bottom of
debian/libgl1-mesa-dri.install.linux.in

I can get i915g to build succesfully on my netbook for both x86_64 and
i386 architectures. I didn't check anything else, since this driver really
only matters for x86_64 and i386. I also tried the resulting driver and it
works fine. Could you please re-enable the building of i915g in the
repository?
