And sadly I can't. Also - is SR-IOV pass-through really related here?
At the point the issue occurs it shouldn't matter yet.

For investigation, could you make the vgabios.bin available
somewhere (might even be small enough to attach to mail)? I
ask because the binary I have doesn't even come close to have
the instruction byte sequence you ran into the issue with.
