Yes, the AV models all have MACE. It's exactly the same chip as in some
early powermacs. I've never tried the macmace.c driver since it used
to be very unstable. I had extra 8390 cards laying around anyway.

I'll try to take a look if I can get my Q840AV running again, but that
may or may not be posssible. Hopefully someone else can take a look
at it before then.

One of my current projects is to make it so we can share a few more
drivers with pmac, and mace.c is one of them (pmac_zilog.c is
first on the list). I haven't had much time to work on it lately,
and several of my macs are starting to have trouble.
