SuSE 9.1 over SATA-Raid SiI-3512

Hi. I'm trying to install SuSE 9.1 Professional over a Seagate SATA-150 200 GB disk. The mobo is a GigaByte GA-7N400 Pro2 rev. 2 (Bios FI) with the SATA-Raid controller SiI-3512 (from Silicon Image). The disk is detected by SuSE, but after partitioning is defined and installation starts, the system hangs (at 2% of installation). If I type ACPI=off, the system hangs too. If I try the "manual installation" and load the sata_sil module, the system hangs while partitioning. Could someone help me?. Best regards. Ventura P.S.: Sorry for my bad english.
