Sorry, I forgot to mention that I did try those options.
Update: I found a dumb typo in my xorg.conf, and now have my 1920x1080__60i custom modeline working great with 9629. Out of curiousity, one question remains, ...why doesn't the 1920x1080 EDID mode display correctly with 9629? It worked fine with 8776.
