Are you using the default ata(4) driver that FreeBSD-8 boots with, or 
are you loading the siis(4) module at boot?  If you are using the ata(4) 
driver, you should try enabling the siis(4) driver by placing 
'siis_load="YES"' in /boot/loader.conf.  Beware that the names of your 
disks will transition from ad -> ada and will likely be renumbered as well.

The siis(4) driver overall has a much richer feature set.  I have 
several 3124 controllers which work great with it, but I have never 
tried using the controllers RAID - I simply use them as disk controllers 
and then pool the disks using ZFS.
