Well, on my model after enabling Hotkey Events, Fn-Fx events are entered
to that variable according to Toshiba, eg.: Fn-Esc would give me 0x101, etc.

I'm at work right now, and will be in the next 2 hours, when I get
home I'll test
whatever patch you send.

By the way, you can find a copy of my DSDT here:
