A bit more testing -- looks like the MacBook Air doesn't mange to get
PP_READY set when it's time to turn the panel on. I should look at this
a bit more closely; there's no reason it shouldn't be set. But, nothing
bad seems to happen if we simply ignore the PP_READY bit

+#define IDLE_ON_MASK		(PP_ON | 0      | PP_SEQUENCE_MASK | 0                     | PP_SEQUENCE_STATE_MASK)
+#define IDLE_ON_VALUE   	(PP_ON | 0      | PP_SEQUENCE_NONE | 0                     | PP_SEQUENCE_STATE_ON_IDLE)
