OK, I'm certainly exposing my relative lack of understanding of
framebuffer issues (I'm here to add a camera driver, remember? :),
but...is this really something that older chipsets can't handle?  Or is
it just that nobody has had that size of panel before?

If it's really not acceptable, then it will stay out, but I would
rather get it merged.  I will leave it in the series for now; it can
come out later if need be.
