You said it is an Intel system; is the over all system an OEM system or a custom assembly?
It's a custom assembly and the BIOS ver 0079 belongs to the mainboard. To be precise, here it is: 

http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&Inst=Yes&ProductID=2933&DwnldID=17562&strOSs=All&OSFullName=Alle%20Betriebssysteme&lang=deu
Can you try using "iommu_inclusive_mapping=1" on the xen boot command line? This works around a VT-d related BIOS issue.
That didn't help. Now that I compiled Xen with debug options, the last lines before the boot process hangs look like this: 

(XEN) [VT-D]iommu.c:1252:d32767 domain_context_mapping:PCI: bdf = 1:1.0
This output is the same, no matter if I boot with iommu=1 only or with both iommu and iommu_inclusive_mapping enabled.
Attached, there's a full xm dmesg of the machine after booting it with IOMMU disabled. 

Tim
