The simple answer is that (afaik) this particular hardware set of hardware has
had trouble since kernel mode-setting was introduce. There is not going to be a
git bisect-able place where the problem started happening.

I do have a question for devs... I have been all over the initialization code
and I cannot find a place where the sideport RAM is treated as distinct from
the UMA "vram".  Is this stuff set up by the atombios? Is there a way to see
what hardware addresses ranges are assigned? Is there a way to fix the GART
(table) if the bios is setting up overlapping or otherwise broken addresses for
GTT, UMA and sideport vram?
