 Not really. I only have a Promise SATA150 myself (I don't remember the
 exact model name). It seems that newer promise don't work with our
 driver :(
 It seems that peoples have had good success with Silicon Image SATALink
 controllers (you probably want the 3114, which is the one with 4 ports). 
 There is also the Intel i31244 Serial ATA controller, but I don't know
 if this one can be found as add-on card.
