They're included in the main tree and, from a quick check, are written by
the manufacturer.

I think the 3ware card meets all of these - there's a CLI as well as a
web interface, errors are logged to syslog and drivers are included with
the main kernel tree.  Another very useful thing is that the individual
drives can still be accessed for SMART monitoring - something most RAID
controllers don't seem to support.  I've actually just picked up a
secord 3ware card (a 7500) - I have several old PATA drives and that was
the cheapest way of getting them all hooked up to the new motherboard!
I would recommend taking a very good look at the 9550 though - the specs
are significantly better than the 9500, not sure how price compares
though.

Cheers,
        Robin
