Did you unbind it from the current driver first? I use the script below
as "./pciback 0000:05:04.0"

Ian.


#!/bin/sh

if [ $# -eq 0 ] ; then
   echo "Require a PCI device as parameter"
   exit 1
fi

for pcidev in $@ ; do
    if [ -h /sys/bus/pci/devices/"$pcidev"/driver ] ; then

        echo "Unbinding $pcidev from" $(basename $(readlink 
/sys/bus/pci/devices/"$pcidev"/driver))
        echo -n "$pcidev" > /sys/bus/pci/devices/"$pcidev"/driver/unbind
    fi
    echo "Binding $pcidev to pciback"
    echo -n "$pcidev" > /sys/bus/pci/drivers/pciback/new_slot
    echo -n "$pcidev" > /sys/bus/pci/drivers/pciback/bind
done
