The 2230SLP will use the 'aaccli' that can be found in the FreeBSD ports 
tree, and can run the linux aaccli that can be found on the CD that 
comes with the card.  I haven't done a lot of testing with this card to
say whether or not it's reliable, but it's definitely a candidate.

I really don't know what I'd recommend.  The aac cards seem to be 'good
enough' for most people.  The amr driver is suffering from instability
under heavy load, unfortunately.  The ciss hardware and drivers are
pretty good, but are somewhat hard to get ahold of.
