If you can't change you PC133 to DDR than I have 2 suggestions for you:
1) ASUS A7V133 (with VIA KT133A chipset - ASUS do not produce chipset at all);
2) IWILL KK-266 (with VIA KT133A chipset).
This two boards have similar productivity and ROCK stability.
Of course VIA have more problems with chipset's compatibility, but VIA try fix all as fast as it possible (fastest whan ALI OR SIS). No doubt that VIA have a best (fastest) non DDR chipset (KT133A not KT133) for AMD processors.
I don't recommend ABIT motherboards (isn't so compatible with all devices), but you can buy it too.
