first of all, you need to hide the PCI device (I guess it''s a
controller-card?). You need to find out the ID of you pci-device:

dom0 # lspci

I can see for example, my onboard network controller:
00:07.0 Bridge: nVidia Corporation MCP61 Ethernet (rev a2)

So, the device ID is 00:07.0
To hide the device in dom0, I use the pciback.hide option in my bootloader:

just add pciback.hide=(00:07.0) to your module line in grub.conf or menu.lst

Next you add the following to your domU config-file:

pci = [ ''00:07.0'' ]

That''s it. If you can''t see the pci device in your domU try to
add the
noirqdebug option to your module line (grub.conf) and your domU config
(extra = "noirqdebug").

Hope it helps,
