I just had a similar issue with a different driver and remembered your post
If the S bits in the infoframe are 0 the display may under- or overscan the
the image (Although the spec says it should behave the same if no infoframe
is present). If it is set to 2 the display should underscan the image, so
I'd be interested to see if the following patch changes the displays
behavior for you.

No change.
BTW, I've been grinding ahead with the EDID quirk infrastructure
changes that I discussed in my previous note. I'd prefer not to waste
huge amounts of my less-than-copious free time, so please speak up if
you have any objections.
