The SuperMicro board linked to is for Intel CPUs (either Coppermine or Tualatin), NOT AMD. It's based on the VIA Apollo Pro 266 chipset, which provides support for DDR SDRAM, as well as regular old SDRAM (hence the "3+2" DIMM setup, though it will not support both kinds of memory simultaneously.)
As far as dual Athlons goes: right now, the only chipset that supports dual Socket As is the AMD 760MP (which isn't even out on the market yet). The board pictured on the Japanese-language site is of Tyan's version of the AMD reference design, which was shown at Comdex in Vegas in November. It is "Extended" ATX form factor and has a 6-layer design, thereby taking it out of the price range of any BP6 owners who may be drooling over it.
Dual Athlons (indeed, dual Durons) are definitely on their way, but we will probably have to wait until the VIA KT266 chipset (AMD processors + DDR) for a practical solution.
