This has not been my experience.  I have been running the 2100S (asr) 
on i386 under 4.x for years now and they are rock solid very high 
performing cards in my experience.  My lesser experience with the 2200S 
(aac) also shows it to be high performing and solid, though my boxes 
with 2200S and 2410SA are still in test mode.

I don't work for adaptec and am sometimes even greatly annoyed by them, 
but their cards have served me well.

I must say I am interested in the Highpoint 1820A SATA raid card 
though.  Anyone use that one and is it bootable under i386 or amd64?
