Hi Daniel,
the patch does work, i.e., it turns off DMAR for the graphics card and
alleviates the freezes when loading i915/kms.
However, still seeing random machine freezes with it (being consistent with the
behavior I've experienced with intel_iommu=igfx_off).
The patch + forcing RWBF is workin

Nice description for what I'm seeing. ;)
After some more hours of uptime I'm inclined to say, that "intel_iommu=off
iommu=off" fixes my random freezes as well.
