Adaptec AAR-1225SA REV A2, Help!

[Raul]

Hello driver gurus!

 I have read somewhere that the adaptec AAR-1225SA is based on SiI3132
and the ata man page says that this chip is supported so I have bought
one of them today.

The chip in fact says:

Silicon Image TM
SII3132CNU
QM2517.1-1
AD02CX2

but sadly, my RELENG_7 (amd64, compiled yesterday) pciconf reports:

none0 at pci0:7:0:0:       class=0x010401 card=0x02449005 chip=0x02441095
rev=0x01 hdr=0x00
    vendor     = 'Silicon Image Inc (Was: CMD Technology Inc)'
    class      = mass storage
    subclass   = RAID

May I do something to get this controller working?

Thanks a lot in advance,
Raul.
