Could you pass the option to the module by creating a file in
/etc/modprobe.d/ to supply the options to the module (the modprobe.conf
explains the format)? I think those files get copied over to the initramfs
when you install a kernel so they should still be used even if the module
is loaded early in the boot process.
Incidentally, you seem to be using xen-pciback in one place and pciback in
another. With a recent Fedora based kernel I would expect you would need to
use xen-pciback throughout.

Michael,
Thank you for the tips. I made sure I specified xen-pciback instead of the
older pciback ... not really sure which line in the configuration it goes
on in /etc/default/grub - leaving it on the XEN line for now. I created
/etc/modprobe.d/xen-pciback.conf to also reflect the same:
options xen-pciback
hide='(0000:00:1a.0)(0000:00:1b.0)(0000:00:1d.0)(0000:01:00.0)(0000:01:00.1)(0000:00:0b.0)'
after making these changes, I updated the grub config file and rebooted.
After reboot, none of the devices are hidden from dom0. I can forcibly
unbind them from dom0 with a script, but that seems messy and some of the
pci devices don't seem to like it (sata controller for example)
Any suggestions?
Gordon
