I think there's a piece missing to this, which is this bit of spec text:
"If no error occurs, the pointer value returned by MapBufferRange must
reflect an allocation aligned to the value of MIN_MAP_BUFFER_ALIGNMENT
basic machine units. Subtracting <offset> basic machine units from the
returned pointer will always produce a multiple of the value of
MIN_MAP_BUFFER_ALIGNMENT."
In i965's intel_bufferobj_map_range, range_map_bo or range_map_buffer
mappings won't have that alignment.
