If you load the module on the kernel command line, try to put the whole
string inside quotes. For example, in my extlinux.conf I have:
"xen-pciback.hide=(01:00.0)" and I can imagine that you could also try
this with grub.

I noticed you have 0000:01.00.0. I see two periods. Are you sure that
this is right? Usually it should be similar to 01:00.0, 02:00.0,
06:04.0 et cetera. Be sure to double check that.

If you would rather not have the xen-pciback line in grub but instead
have the module be loaded during boot or via a manual modprobe, then be
sure to have something in /etc/modules.conf or /etc/module.d/custom.conf
(or another name of your own preference) like the following:

options xen-pciback hide=(01:00.0)(02:00.0)(06:04.0)

After that, run update-initramfs. Usually I just do either
"update-initramfs -k all -c" or instead of -c (create new initramfs)
I use -u (update existing initramfs).

If that does not work, try to put the full string of the last element
in quotes and retry again.
