With the introduction of FreeBSD 9.x, all ATA devices now use a
translation layer (ATA->CAM), and this is especially so with anything
SATA.  I imagine this needs to be documented (in red, bold, etc.) in the
official 9.0-RELEASE documentation, because it's probably going to trip
up others.  But, things of this nature are supposed to be documented in
/usr/src/UPDATING, and admins are *expected* to read that file.

As such, going forward, you're going to need to make sure you have SCSI
support in your kernel config, including "device da" and/or "device
ada" (not sure on the latter one).

You'll also need to make sure any of your old rc.conf, make.conf, config
files that reference ATA devices (/dev/adXX) etc. are all updated to
reflect the new device naming convention.

Finally, please be aware that when transitioning between FreeBSD
versions, you cannot 100% reliably/safely copy your old kernel
configuration file.  You really do need to go through and "migrate"
your kernel config to mimic what's in /sys/{arch}/conf/GENERIC.
