Ok, I must say I'm a little confused by the title, but anyway, yeah there are planety of KT133A motherboards with support for Sdram, in fact, all KT133A motherboards only support Sdram. If you want a motherboard that doesn't offer any better performance with DDR and Sdram dims, look into the A7A266, well I can't say no performace gain, but it is minimal, especilly Seeing how it's running on the Ali chip.
