    I tried this already before. Same result:

    [root@ws22 /]# insmod parport
    [root@ws22 /]# insmod parport_pc io=0xefe0
    [root@ws22 /]# tail /var/log/console
    ...

    [root@ws22 /]# rmmod parport_pc
    [root@ws22 /]# insmod parport_pc io=0xefa8
    [root@ws22 /]# tail /var/log/console
    ...
