You have the same drive I have.

sata_sil is the libata driver, it doesn't support "hardware" RAID. Enable CONFIG_BROKEN to compile it, siimage is the generic ATA driver (and supposedly the safer of the two, but I've had no problems (yet) with sata_sil).

Try 2.6.2-rc1 using the sata_sil driver, it has a blacklist instead of punishing all Seagate (and Maxtor) drives, and ST3160023AS is definitely not blacklisted at all, regardless of chipset revision. Revision 2 or newer of the SiI3112 should be fine with all Seagate drives.
warning: your /dev/hdY will become /dev/sdX (probably /dev/sda, in your case) if you go from the IDE (siimage) driver to a libata (sata_sil) driver.
