Intel HD2000 VT-d IOMMU fails boot of Windows 7 (VB hang)

[mhakali]

Trying to import two devices via VT-d / IOMMU.

VBoxManage modifyvm "Windows 7" --pciattach 03:00.0@01:05.0 VBoxManage modifyvm "Windows 7" --pciattach 00:02.0@01:06.0

Kernel: 3.2.6 Ubuntu branch with Tresor AES patches. IOMMU and DMAR enabled and verified (working USB3.0 device import)

03:00.0 USB Controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev 04) (prog-if 30 [XHCI])
	Subsystem: Intel Corporation Device 2008

00:02.0 Display controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
	Subsystem: Intel Corporation Device 2008
	Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
	Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-

	Region 4: I/O ports at f000 [size=64]
	Capabilities: <access denied>
	Kernel driver in use: pci-stub
	Kernel modules: i915

The host is running on an NVidia card. Neither i915 nor xhci-hcd is loaded as kernel modules.

The USB3 succeeds import. The Intel GFX creates a crash on Windows 7 boot.

Have not found any clear instructions to how to assign guest device PCI-ID's, so just took two examples as found in the advanced settings documents.

Tips and/or workarounds appreciated.

Attaching virtualbox logs.
