 * PARAMETERS
 *  irq_mode=n
 *     Specifies the interrupt delivery mode.  The default (1) is to use PCI

 *     correct operation of PCI card readers.
 *
 *  irq_list=i,j,...
 *     This list limits the set of interrupts that can be used by PCMCIA
 *     cards.
 *     The default list is 3,4,5,7,9,10,11.
