I have not seen any complaint yet. Theoretically it should select dispatch scheduling if "-march=bdver1 -mdispatch-scheduler -O3" flags are selected. Otherwis the behavior should be the same as before.
If you think the bug that you noticed is related to this change, please file a bug and let me know, and I will look at it.
