ATI should hopefully give an update soon. As for now, there are no "good" drivers for these cards. You can look at the table here for the driver information that Tom's used when they were testing them in crossfire if it helps at all.
The ones on the disc are the only ones that work so far, Today was said to be the day the 9.5 drivers come out but they are not on the AMD/ATI site yet.
