I don't understand why they went to SDM in the first place - it makes no sense to me! What's wrong with the old screw drive mechanism, it's simple and reliable.
Because if you're Pentax and even Sigma can do sonic motors and you can't, the marketing folks get a bit upset

In my experience, SDM is much quieter and faster (Perhaps not by much)

Pentax could pull a clever move by releasing the firmware of older models to the opensource/enthusiasts and watching developments! Might give them good ideas for future products!
Not official by any means.
I believe I can swap to screw drive on my DA* lenses by going back a firmware on K10D.
