Thanks Ron for the heads up, now I have a working DA 16-50mm again!

I put my K-x into debug mode per instruction found online, then found the menu to write out lens rom from camera to SD.  Followed the instruction to edit the required lines, wrote the rom content back to the lens, and voila!  The lens can focus again!
