Patch splitting to come. So far I've tested on a 945gm and PineView and
both are happy with the legacy PendingFlip status mode. And Daniel has
tested on a 915g which was demonstrating the same trouble as our dear
bugzilla reporter. One person I'd like to see I can get testing is Simon
Farnsworth if he still has only of his 945s available for testing.
