impressive! How did you succeed?

I've started looking at two possibilities:

-Trapping ar5416GpioSet with some hand crafted assembly code that traces calls 
and logs them somewhere (maybe an unused module like fuse could provide kernel 
space to scribble the logs ;-) Now that you decoded the init and disable 
sequences it should be possible to find a command in such a log.

Any hints?
