I did that change... The spec says the table is termined with 0x0000 and
testing only 8 bits makes the code stop parsing before the end as some
valid entries can start with 0x00 (I had actual examples of that).

However, I don't know about the i > 1 thing. I assumed it was a hack to
workaround the former bug, it didn't make much sense based on the spec.
However the spec also provides a connector count so maybe I should test
that too.

In any way, I don't know for sure what's up with Xv, unless we end up
flipping CRTC1 and 2 but I'm not sure how/why that would have happened.
