You'll need a kernel with PCI support and a driver for the device in question.
YOu could just use the xen0 kernel.

Sounds sane. Note that the syntax is different for physdev_dom0_hide
(something like "physdev_dom0_hide=(00:11.0)" should work but you should
check your xm dmesg to be sure the device has been correctly hidden).
