  It contains the IRQ, the GPIO address, and the mode, same as in the
config file :).  In isa_machdep.c: 

         * 'intr' encoding:
         *
         * 0x0000000f ISA IRQ#
         * 0x00ff0000 GPIO port#
         * 0x01000000 interrupt signal hold/through     (1:hold/0:though)
         * 0x02000000 interrupt detection level         (1:low /0:high  )
         * 0x04000000 interrupt detection trigger       (1:edge/0:level )
