DDR2 Dual Channel 800mhz is like the toyota camry of ram, I'd be abso-fucking-lutely shocked if the Mobo didn't take it.
It should list it, but I would feel safe in making that assumption, yah.
*Edit - Yup, in fact the Athalon X2 chipset only supports UP to 800mhz ram, so you'd be sunk with that 1066 again.
Newegg reviews confirm people have used ddr2 800

A common mistake people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools. Douglas Adams
