If I'm reading that right, all your presses without Fn are the same as mine. In that case your keyboard switches and scanning hardware/software is all correct. But your Fn presses are different. I'm not sure if the operating system can change that; I don't know what level the keycodes come from. It could be anywhere between the keyboard firmwear to the operating system. If you choose a different keyboard layout for the operating system, either the keycodes will change or be the same. I'll try this later if I get a chance.
I have been unsuccessful trying. I cannot make my keyboard layout change within X to use xev. But at this point, I'd recommend reflashing the keyboard firmware. My best initial guess is that's where the problem lies.
