+Subject: [PATCH] nvc0: Disable BGRA8 images on Fermi
+
+For unknown reasons, using BGRA8 images on Fermi results in breaking
+reads from PBOs, such that they always return 0x0. Discovered this
+through a glamor bug, and confirmed it does indeed break a good number
+of piglit tests such as spec/arb_pixel_buffer_object/pbo-read-argb8888
+
+Until we have a proper fix, just disable this functionality on Fermi.
