Please find attached a patch I use with my ich9 board.
The original author wanted to check some registers before commiting but I 
heard several times that ich8 and ich9 are identical regarding ATA.
I'm using AHCI and it works fine, although I have some CD-Rom problems too 
(ATAPI) but haven't hd time to track it down (mostly burncd makes trouble)
