Actually, based on the thread going on on -stable right now, from ppl that 
are talking to Adaptec, the issue is that the cards that use the iir(4) 
driver, at least as far as I'm reading things, are no longer considered 
supported ... Adaptec / ICP Vortex *is* coming out with newer cards, that 
will be supported by FreeBSD, but they won't fall under the iir(4) driver 
...

So the problem is more 'older cards with newer operating system' ...
