My IAL replacement code does not support A3 revs.  To fix that you need
to add to the qmgr support as the A3 hardware does not have certain
functionality the current code assumes.

I assumed A* boards would be rare; am I wrong?

(since we don't have proper bootstrap support yet to pass that in from
redboot).
