Hello,

so you can not Passtrough PCI Devices to a HVM guest without an IOMMU 
because Direct Memory Access (DMA) is managed with physical addresses. 
What you could do is passtrough a USB device with a few contraints. For 
this look on this page: http://wiki.xen.org/xenwiki/XenUSBPassthrough
When you don't have an IOMMU you only can passtrough PCI devices to a PV 
DomU so a Linux, BSD or Solaris.
For giving an answer if it also would be possible to solve your problem 
with other methods it would be helpful to know, which specific problem 
you have.
Best Regards
