You know these are only relevant to control the generation of an 
interrupt signal ?
To mess with these, you will need to set up an interrupt handler.
I can help here, as when I was messing with the ethernet interface on 
the Devkit, I setup an interrupt handler then, as it uses a GPIO line 
as an interrupt.

Don't forget the Camera port !!

If it was missing in the earlier versions, its not in the later/latest 
ones...
