Is it possible the driver code for the LED controller used by fglrx can be
released to get the ball rolling on this? Someone I should get in contact with
perhaps? Or is this actually being worked on (or at least scheduled to be
worked on) internally at AMD?

It's been almost six months since this regression was initially reported (I am
told the free software stack is the AMD-recommended upgrade path for consumers,
so I feel justified in calling it a regression from that perspective). I know
the AMD devs are busy people, but it would be great to see some progress on
this before the cards I purchased are eventually retired.
