I searched, ended up on the Asus site, and saw that there are BIOS' out for KT133 chipset based mobos to support Morgan Durons. Looks like a good sign if you ask me.. I think your best bet would just be to either talk to someone at a computer store that knows his stuff, or call Abit if you can't find it online... the best thing to do is to talk to someone, that always makes me more comfortable...
