Most ASUS motherboards for AMD processors and some Gigabyte motherboards have ECC support.
On the Intel CPU side, the X38/X48 supports ECC with DDR2 memory, Again, many manufacturers don't have ECC support with their motherboards, but ASUS and Gigabyte often do with those chips.I don't know what the story is with motherboards for the Core i7 and ECC.
