Hey! It works great! Thanks Andreas!
All, I can take on working up a patch to do this by default on the 900a 
(testing on all current kernels). Where should I send/submit the patch 
once it's ready? Andreas, let me know if you would prefer to take the 
lead or corroborate on this. I don't usually boot from the pre-ath5k 
kernels, but I can definitely do so for testing purposes.
