I haven't read every bit of this thread, so perhaps I've missed the
point, but my ION board seems to play back 1080i fine. I have to
use Temporal x2, but that seems to do a really good job. Before
buying the board, I'd read that it couldn't handle Advanced x2,
and that Temporal x2 wasn't as good, so I was expecting to be
really dissappointed, but it seems to give really a sharp image
with smooth motion, and no noticeable artifacts. I don't know
what more you can expect from a deinterlacer.

One strange thing is that I see combs when I pause playback,
which I never saw before when using yadif and software decoding
of SD.
