IRQ line is not neccessary (i hope), but the patch puts this to
suspend path:

/* Switch to loopback mode to avoid hardware races. */
iowrite8(rp->tx_thresh | 0x02, ioaddr + TxConfig);

/* Disable interrupts by clearing the interrupt mask. */
iowrite16(0x0000, ioaddr + IntrEnable);

/* Stop the chip's Tx and Rx processes. */
iowrite16(CmdStop, ioaddr + ChipCmd);

(this was copied from shutdown path of the driver)

I suppose that the first one might break WoL. Unfortunately
on my hardware the WoL don't work even without the patch.
