Will do! And actually, to be precise, the issue occurred not on the rmmod, but on the following modprobe for ath9k.

Linus has been fairly strict lately, so I am as uncertain as you are. It really should get merged, because having 2.6.27 with [partially] broken wireless networking is kind of stupid. In the worst case, isn't it possible to do a revert to get the old aggregation crap back in?
