This should be a problem.
Could you increase time of DELAY() in fwohci.c and try again?

/*
 * probe PHY parameters
 * 0. to prove PHY version, whether compliance of 1394a.
 * 1. to probe maximum speed supported by the PHY and 
 *    number of port supported by core-logic.
 *    It is not actually available port on your PC .
 */
        /* Wait a while */
        DELAY(100);
        ^^^^^^^^^^^
        reg = fwphy_rddata(sc, FW_PHY_SPD_REG);
