BIG FAT NOTE: Theres a nasty bug somewhere thats causing vb color buffer clears and other things not to work. This bug can be triggered by extending struct r300_hw_state by two struct r300_state_atom's from its current size. Everything zbs and unk42B4 related is now covered with HAVE_ZBS and GA ifdefs. Who wants to fix it? Not i. :)
