Yeah I have an AP but it's broadcom based.  I'll try to do the traces this
weekend.

Well, with the change from my original post, the card appears to
function somewhat but the cpu gets busy and the whole machine crawls.
Note, I didn't make any changes for initvals.  

I can associate but not for very long.  dmesg looks like this:

ath5k phy0: Atheros AR5424 chip found (MAC: 0xa3, PHY: 0x61)

and sometimes:
ath5k phy3: noise floor calibration timeout (2462MHz)

With debug on these were the resets I was seeing, may be normal but I
didn't know:
