hmm.. not sure if this is even being read or not
as a simple test:


    		/* CSC interrupt: no ISA irq for CSC */
  -		reg = exca_readb(socket, I365_CSCINT);
  -		reg&= I365_CSC_IRQ_MASK;
  +		reg = 0;
  +		if (!socket->dev->irq) {
  +			reg = exca_readb(socket, I365_STATUS);
  +			/*reg&= I365_CSC_IRQ_MASK;*/
  +		}

just a simple STATUS on this still errors out with the
unsupported card thing..
