Orientation change in Honeycomb

I have an activity that shouldn't be recreated after an orientation change. I added the following to the activity declaration in the manifest:

android:configChanges="orientation"

On Android 2.3 this works perfectly. On HONEYCOMB_MR2 onCreate is called anyway when change the orientation.

Is there something else that needs to be done on HONEYCOMB_MR2 to prevent recreating the activity after an orientation change?
