It may also be called xen-pciback.hide in some kernel versions, I''m not 100% sure about the Squeeze kernel but bear it in mind.

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. Thanks a lot Marius

"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.
