The latter, most likely. Otherwise, FreeBSD wouldn't see the
individual drives, the RAID controller would show up as a SCSI
controller and the array would show up as da[0-9]+.

Since you just want mirrored drives, you don't even need the RAID BIOS
to boot, so: yes, you were conned. Provided you leave a little space
at the end of the disk, you can set up mirrorring after you're done
installing (off the top of my head and totally untested: 'atacontrol
create RAID1 ad0' to create a single-disk mirrored volume followed by
'atacontrol addspare ar0 ad2' to add the second disk; you may need to
'atacontrol rebuild' to initialize the second disk; and sos@ will
probably kill me for getting the instructions all wrong)

Only if its on-disk layout is compatible with the Promise or Highpoint
