DIO cards with edge-triggered interrupts

Hi,

I am developing a comedi driver for a winsystems PC-104 based DIO board. 
The neat thing about this DIO board is that it supports edge-triggered 
interrupts on 24 individual DIO lines.

Since I am too lazy to research this myself, could someone just tell me
how edge-triggered interrupts are modeled using the comedi driver 
framework?

Basically how can I give this functionality to the user of the driver 
using the comedi API and framework?  It's not exactly a comedi command and 
it's not exactly a comedi_sv thingamajig.  Or is it?

Any advice is appreciated before I go willy-nilly and implement my own 
proprietary IOCTLs to piss everyone off...
