Thanks for this!

I'm sorry it hasn't gotten any more attention. I've cc'ed john because
he understands the PCI-PCI resource allocation stuff and I currently
don't; I'm hoping he can stare at this and see what's going on.

But yes, if it were an ath(4) problem, the NIC would be returning
0xdeadbeef, 0xdeadc0de, etc. It wouldn't return 0xffffffff - that
happens when there's nothing mapped at that address.

The PCI config space that you've provided shows BAR(0) is programmed correctly..
