Ok, so I did -b and -g traces.  That branch is a little out of date, so 
I wound up downgrading to 2.6.22.

I don't have an a-capable AP, so how might I get a/turboa/turbog traces?
Do I use wlanconfig from the madwifi docs like so:

   $ iwpriv ath0 mode 1
   $ wlanconfig ath0 create wlandev wifi0 wlanmode ap

What mode # is used for turbo a/g?

I put the tarballs at http://bobcopeland.com/ath5k/

Looks fine, I think:
    Quality=89/100  Signal level=-39 dBm  Noise level=-96 dBm

OK, well I guess that info is in the tarballs.  I poked around in the
code, and it looks like my tables are similar to 5413 with maybe a 
couple of extra registers.  But I'll await your analysis. :)

It does get rid of the message, but other than not seeing the printk
any more, it doesn't seem to help things much. 
 
Good luck on the exams!
