i.MX21 (ADS21) GPIO interrupt

Has anyone had success creating gpio interrupts for the ADS21 board?  I looked at the GpioClass.cpp and the mx21ddk.dll, they contain methods to access gpios and enable/disable interrupts, but I did not find any methods to catch a gpio event from which I can call from a managed code application. 
The alternative that I thought of was to extend the keyboard library, i.e. make it more than 6X6 as used in the board. 
Any pointers where I can find information/documents on how to implement any of the two points above is appreciated.  Also, if this is the wrong forum to post this kind of question, I would appreicate it if you could point me tot he right forum.  Thanks.
