AFAIK interrupt numbers for GPIO start with 160 and then are 
numbered starting with first GPIO bank and so on.

See include/asm-arm/arch-omap/irqs.h:

#define IH2_BASE           32

/* Max. 128 level 2 IRQs (OMAP1610), 192 GPIOs (OMAP730) and
  * 16 MPUIO lines */
#define OMAP_MAX_GPIO_LINES     192
#define IH_GPIO_BASE            (128 + IH2_BASE)
#define IH_MPUIO_BASE           (OMAP_MAX_GPIO_LINES + 
IH_GPIO_BASE)
#define IH_BOARD_BASE           (16 + IH_MPUIO_BASE)

Have a look to GPIO framework in gpio.c and its usage in 
various files which can help you programming GPIO stuff.

Cheers

Dirk
