If you're referring to the FastTrak and UltraTrak RAID cards they claim they already support Linux - even if only at the binary level. The unfortunate part is that they only support really old distributions with fixed kernel versions. I gave up on them long ago.
Your best bet is to add the card in question (which card are we talking about here?) to the H C L
and rate it for compatibility.
oh, and moved to the Linux - Hardware forum
