Okay that would be good.  I was basically searching for differences by
hooking ath_hw_reg_write with a printk, sorting that, and diffing it
with a sorted file of "reg_address:value" extracted from the traces.
Would be useful to run the same scripts over other cards' dumps...

I did a few times, but not enough to definitively say which works and 
which doesn't.  I'll try to get it repeatedly starting up correctly when
I get some free time, and from there I should be able to figure out 
what's actually needed and what is noise.

Sure, I'll give that a go as well.
