Sorry, I can't help you anymore than my last suggestion, I have an 
onboard promise ATA100 controller (Asus A7v board), which is why I 
noticed the kernel option, but I don't know anymore about it. I have (I 
think..) DMA working, with the kernel autodetect DMA flag set (I don't 
know the exact names of the flags - I don't have a linux box handy ATM) 
and I might or might not have the promise DMA flag set, but I don't know 
if my setup would work with your promise raid controller.
