errr I think that Gigibyte made an AMD 750 based socket A board, (don't remember the number, but you could go to their site and find out which one that is), beyond that, I think thats about it. Though there may be more socket A boards based off of the 750, or you could try to find a 760 DDR board or a ALI MaGiK board, but both of those are very expensive if you can find them at all, and would require purchasing new ram, the 750 boards will just run it at 100 mhz even if you have pc133, but it should at least work, make sure it doesn't have a via south bridge though, cause if it does it still won't work.
