Adaptec eSATA II RAID 1225SA
I ran into a number of issues making the Adaptec eSATA II RAID 1225 card work under linux. At first it showed up as a RAID bus controller: Silicon Image, Inc. Unknown device 0244. Turns out the pci id is missing out of the current kernel. In order to make it work you need to edit sata_sil24.c and add in the device ID 0244. Once you do this the driver sata_sil24 will detect the controller and all will be well. I also found that initrd decided to make the estat disk /dev/sda which confused my boot order. As such I excepted sata_sil24 from initramfs



Did it work well? Have you reported this to the LKML?
