I would rather not include anything that can't be tested at this point.
IIUC the IOMMU is still only for the video devices, which I omitted at
all so far - the display engine definitely needs code changes (Jernej
has something in the making).
So I'd like to wait for the IOMMU nodes till we get DE or VE support.

Andre
