[PATCH][Karmic]drm/i915: fix tiling on IGDNG

[Zhao, Yingying]

The attached patch brings 50% performance gain compared with non-tiling in 3D games like Open Arena or Unreal Tournament on next Intel embedded GMCH - Ironlake.

It's already accepted by upstream and is expected to be in 2.6.31.2.

Please consider to get this patch into Karmic.
