That won't work. That option is only useful if pciback is compiled
in the kernel. To be exact, you would need this in your bootline
argument:
 xen-pciback.hide=(04:07.0)(04:06.0) pci=resource_alignment=04:07.0

Since it is module you need to follow the documentation about how to
seize and bind using pciback. Google is your friend.
