Sorry for the top posting, web email has ruined my mailing list
etiquette.  It seems having the correct firmware in place has caused
some forward movement.  I now see this:

Occasionally my kernel is panic'ing at random spots (this is probably
related to the other patch I guess), but I do have a bit of an adapter
now ,ifconfig shows it.  I don't seem to be able to find any networks
with it however.
