Ok, apparently the Kwikset locks should work just fine with R066, but it turns out that there are some specific steps that needs to be taken once the locks have been installed.
The procedure is as follows:
Press and hold the Lock button while installing the battery pack.
Hold the button until the latch bolt starts moving on its own.
The latch bolt will retract and extend on its own a few times
to learn the orientation of the door.
When the latch bolt stops moving and the Status LED
flashes green, the door handing process is complete.
Once this had been done, you can add the lock to the Almond+ and it should behave properly with firmware R066 or later.
I've also uploaded PDF's with pictures that show's exactly how to do this on the Wiki -
