I am tring to find a solution for that same problem too. Had the same PCI ATA card in mind. The information I got was realy controversial, everyone says different things realy difficult to get by this way, I guess its back to trial and error.
For an example, look at the email I got from Promise HQ support, after I asked them the same question:
[I] > Dear okeke,
> Yes the Ultra133Tx2 also support ATAPI devices.

now why would he state that if it wasn’t true??? but then kwkard seems to be speaking from experience, so what is the fact then???
