As I was staring at the si_init_golden_registers code, I noticed that the Pitcairn initialization silently falls through the Cape Verde initialization, and the Oland initialization falls through the Hainan initialization. However there is no comment stating that this is intentional, and the radeon driver doesn't have any such fallthrough, so I suspect this is not supposed to happen.
