I gather that this is just a revision of the Intel motherboard chipset drivers. If it's well-written it certainly could accelerate certain disk- and memory-access functions, probably improve stability too...but I read that a lot of people saw no improvement with first "release" of these, and apparently some people had real problems with peripherals not working right after installation. I'll wait until Anand or some other brave authority figure runs it on a few testbeds...
