WInterrupts.c is confusing with all the defines, but this looks relevant:

Code:
    case 4:
      EICRA = (EICRA & ~((1 << ISC20) | (1 << ISC21))) | (mode << ISC20);
      EIMSK |= (1 << INT2);
      break;

Given that you want an INT2 interrupt, it looks like attachInterrupt (4, foo) is what you want. Try it anyway, and see what happens.
