perhaps not exactly the information you want, but I own amass storage controller from Promise Technology (SATAII 150 TX4, rev 02) and run 2 SATA1 drives with it. These drives are part of a raid-array and are running flawlessy. If you have problems with your mobo, you could think of buying such a card as an alternative.
