"xen-pciback.hide" is a kernel module option for the "xen-pciback" module. I think you should check the output of "xm dmesg" and see if IOMMU is enabled in your dom0.

oh my fault. It should be a kernel command line option. For debian
squeeze with kernel 2.6.32-5-xen-amd64 xen-pciback.hide is the right option.
