You have the hardware, so that should be a straightforward change. Thanks for the suggestion! That makes sense. I will start working on converting i6300esb and submit a patch in a few days. By the way, I don't have the hardware. I'm using it with KVM (Qemu), but I guess that's good enough since I'm not going to touch any of the code parts that deal with the hardware.
