May be that it works as a standard IDE controller, not necessarily as a RAID

Not too much help I'm afraid, but I wasn't confident in the abilities of such 
a cheap controller (mine cost me GBP £20, about USD $30) to work well, 
particularly with FreeBSD. I just set mine into "standard IDE contoller" mode 
(there was a jumper on the board to control this), and have set up a mirrored 
RAID 1 with vinum.

So far it's running fine like this.
