So I actually ended up testing the patches, and first they fail to
compile against current mainline (trivial fix attached), but then
the guest (also latest mainline as of today) also hangs during the
initialization of th i915 driver on i7-8550U-based Thinkpad.  Plain
mainline as the host boots fine, but spews a lot of warnings.

Host and guest configs are also attached.
