CPU-Z lists my SP5100 as an SB750, actually. It's kind of funny. Unfortunately no, though, I need support for my specific clock generator. It's a different one than those used on virtually all 700-series boards.

If I limit Windows to 4 CPUs, AOD will load. I just don't have control over HT ref. Of course, it would be of limited usefulness to only be able to run with 4 CPUs, but it would have been a start. Apparently AOD crashes if it doesn't have enough display spaces for the number of CPU cores or GPU cores in a system.
