Indeed, I remember when I was doing some mining early in bitcoin's history. I had custom hacked BIOS on my AMD cards to be able to overclock beyond regular power limits. This flashing was possible only due to an exploit of the BIOS signature verification. Given that I was doing this as only a rather casual miner with three GPUs, I have no doubt that this new restriction will be attacked ruthlessly.
