Check out Dave H.'s gpio-event driver. I know it used to be in the gumstix verdex repository, but might also be in the overo one. It contains a driver and user space program that is pretty easy to follow, especially if you reference back to the LDD book.

Yeah, so this section does suggest one could signal interrupts to a
