DIO Change Detection

Does anyone know of any Comedi-supported board that can do DIO change 
detection (in order words, generate an interrupt to the CPU whenever 
digital input lines change state)?

I know some boards out there can do this, but :

1. It isn't immediately obvious to me that the comedi_cmd interface can 
clearly express this..

2. Even so, do any comedi drivers support this feature on any boards that 
my have this as a feature?
