hi,

> i "followed the rules" for method 2 ...

not at all sure why that was NOT working for me, but, the following:

grep pci /boot/grub/menu.lst
	...
	module /vmlinuz-xen ...
	pci=resource_aligment=0000:05:07.0;0000:02:00.0;0000:03:0.0

rm /etc/modprobe.d/99-local.conf

cat /etc/init.d/boot.local
#! /bin/sh
DEV="0000:02:00.0 \
     0000:03:00.0 \
     0000:05:07.0 \
    "
for BDF in $DEV
do
        [ ! -e /sys/bus/pci/devices/$BDF/driver/unbind ] || \
                echo -n $BDF > /sys/bus/pci/devices/$BDF/driver/unbind
        echo -n $BDF > /sys/bus/pci/drivers/pciback/new_slot
        echo -n $BDF > /sys/bus/pci/drivers/pciback/bind
        echo -n $BDF > /sys/bus/pci/drivers/pciback/permissive
done


now, @ reboot,

dmesg | grep -i seiz
	[   33.277131] pciback 0000:02:00.0: seizing device
	[   33.308782] pciback 0000:03:00.0: seizing device
	[   33.358124] pciback 0000:05:07.0: seizing device

apparently correctly seizes all the devices, as intended. (note the much
later timestamps ...)

and, in my DomU,

lspci

thanks!
