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

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?
