Sounds like that adapter isn't supported on 5.4.
There is a lot of new RAID support in newer branches of FreeBSD, but I
don't know what hardware is actually in that card to tell whether it
should work now.  

You should try 6.0 (or, preferably, one of the prerelease versions of
6.1), and maybe talk to the driver maintainers.
