I see the answer here is no.  The approach is:

 - Install onto ad4 (or ad6).
 - Create ar0 using atacontrol.
 - Reinstall and ar0 will be offered as a destination disk.

On this point, would I be better off waiting until ata(4) can
recognise the ICH6 metadata and restart the process using a
BIOS-created RAID1 array, or is the ata driver-based RAID1 array
created above just as robust?
