I have a S2885.

I made a simple modification to the driver which essentially maps the 3114 as
a 3112, which works, sort of (not with the recent changes though, I'm getting
those "TIMEOUT - ATAPI_IDENTIFY retrying messages" that others had mentioned
as well). The drives do not go into SATA DMA mode (150Mbps), but I have the 
slight suspicion the code doesn't really support those yet with the SiL chipsets.

On very high load on the drives, I sometimes get 
  ad4: WARNING - WRITE_DMA UDMA ICRC error (retrying request)
style errors, but all in all, it's working very nicely.

Note: this is a FreeBSD type ATA-Raid, there's no support yet for native
RAID that is understood by the BIOS.
