I took the hand rest off, and I was pleased and surprised, by the results!
The buzzing from the D string was gone, just as I suspected, because I can now dampend right at the saddle.
In fact, with the hand rest out of the way, my ability to shape the sound of the instrument greatly increased, too, because I have so much more space to move my right hand around in. A brush right in front of the saddle gives a nice effect, too.
I am not at all worried that I will somehow manage to crush the cone be merely playing it. And, I should add that I rest my palm right on the saddle, just like a normal, acoustic guitar. The danger to the exposed cone will only arise from some avoidable accident where the biscuit takes a direct blow. The damping and sound control I've gained are worth the risk to me.
So, my solution, for now, is to attach the hand rest back on with masking tape for when it's in its case, or I'm leaving it out of the case, but standing in a guitar stand.
