I am trying to remember how I did it with a PCI card. I think you
need a file in /etc/modprobe.d that lists the gives the options for
parport_pc as io=0xb480 irq=11. Something like a file called
parport-pci.conf with this as the contents:

options parport_pc io=0xb480 irq=11

You may need io=0xbc00 instead of io=b480. You will have to run
depmod after making the changes, remove and reinstall the parport_pc
module, before the changes will take affect. (Or reboot.)
