Just to reiterate, this won't work for the radeon driver, which programs
the GPU to use (effectively, per the current definition that these are
little endian GPU formats) DRM_FORMAT_XRGB8888 with pre-R600 and
DRM_FORMAT_BGRX8888 with >= R600.

BTW, endianness as a concept cannot apply to 8 or 24 bpp formats.
