There are three pieces and I may have confused you.

+ current stack in tree
+ some add on drivers with porting kit
+ new dual mode stack

I do not think there is an smc driver in the add on kit. I just thought if you decided to use a new driver with the old stack, it would be a good reference.

The new stack may be an option. It would have the latest drivers but has not been tuned at all. We know it is larger than the current stack but I do not know if the performance has been measured.

I am not recommending a solution. Just offering more possibilities.
