 Looking at the diffs between those dumps, I wonder if the problem
 is/was that your machine has bad RAM, or some similar problem :(
 for example: 
   ohci0 at pci0 dev 3 function 0: PCI configuration registers:
     Common header:
 -     0x00: 0x70011039 0x82800017 0x0c03100f 0x00804000
 +     0x00: 0x70011039 0x02800017 0x0c03100f 0x00804000
 Not related to the atheros card at all; but it seems like that should
 not be different from one boot to the next. Although I don't know what
 it actually means so maybe I'm jumping to conclusions.
 In any event I suspect the interesting part (within the atheros
 section) is this:
 -       Parity error detected: on
 +       Parity error detected: off
 and that this state caused it to not attach.
 However, it was all long enough ago that you've probably junked the
 hardware in the meantime... I hope you found a way to make it work
 reasonably reliably, as opposed to just "sometimes".
 I think at this point the PR should be closed...
