Feeling a little embarrased here chaps!
I fly the -800 and never even knew or thought of this problem. What are the indications of catching the cabin. My airline flys to some very quite airports so we often use high speed, high descent rate appraoches. This problem has never been brought to my attention?
From your discussions of the Air Cond/Press configuration I am presuming that the setup is a little more similar to the 200 of which I have a passing knowledge.
