i'm in this very same boat. currently i have some systems running with mylex extremeraid 2000 cards but i have not been overly impressed with their stability in either linux or freebsd.

actually, both the 2200S and the 3210S have the same processor in them. the 80303 processor is 100Mhz. the specs state 64bit/66Mhz 80303 processor but that is only in reference to the bus rate no thte clock rate. the 80302 is the 66Mhz version and is included on 21xxS boards and below.

you would want the 2200S if you're planning on upgrading to U320 drives though. this brings me to my question: is the adaptec 2200S supported under freebsd 4.8? has the asr driver been updated for U320 support or no?

yeah, don't use the Mylex cards! ,)
