i don't think it will natively support a tualatin. you need a apollo pro 133T for that.
but i think it can be modded (either the board or the cpu) to run tualatins.
i don't expect there would be any problems running 1.0A and 1.1A celerons at 133 fsb. 1.2 might do it, might not. 1.3 and 1.4 are unlikely to run at 133 fsb.
