I am running an Adaptec 2410SA 4 port SATA raid card on x86_64 in FC4 
and have had no problems since the third or fourth kernel update of 
FC3.  I recently copied my entire array to another network server, 
upgraded my firmware on the card and rebuilt the array, and copied 
everything back... about 200GB.  My only trouble is that I can't seem to 
get the raid tools working. But I haven't really been working on that 
since about mid FC3.
