Truth is, is that nobody knows. AMD hasnt confirmed or denied it. Me, I would be suprised if Palomino ,err... Athlon 4 lol, is able to run on current Athlon motherboards.
Most, if not all, KT133A and DDR mobos are capable of supporting Palomino. However, a BIOS upgrade may be necessary (depending on your specific mobo/bios).
