Do we have igt testcases that try to exercise all this? When fixing bugs,
pls make sure you don't fix the bugs, but also make sure we have solid
coverage. Given that this escaped for years, it's very likely our coverage
is _really_ bad and needs to be improve a lot for testing interlaced modes

Thanks, Daniel
