Yeah, our ServeRAID driver lacks recent important updates from FreeBSD-CURRENT
including newly supported controllers and a few bug fixes.
not sure if freebsd 5.3 driver is that good. I have open PR 
(http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/71087) for it.

 The update
in FreeBSD-CURRENT also involves converting some of mutex operations into
sema_* and bio*, but I haven't managed to rewrite it using our native
thread APIs. Anyway, I can post a minimal patch(that is, not including my
experimental code to convert the mutexes and the semaphoe stuffs) to support
newer controllers if you like to try it.
I did this for FreeBSD 5.2.1 to make it work:

It is a hack, but it works fine.
I would say something like this should not go into main Dfly code, but 
something close would make Dfly usable for people with new cards.

Yes, I will gladly test it if you prepare a better patch than my hack.
