Yes, seems so. FWIW, this patch is in later Fedora kernels.
Unfortunately (due to the ieee80211.c -> rx.c issue you mentioned)
applying this to 2.6.23 conflicts with patches already queued for
2.6.24. Since my experiments show that git doesn't help much in this
instance, I'll need to work something out with Dave M. if we are to
get this into 2.6.23.
If nothing else, I suppose we can just wait for 2.6.23 and send this
patch to -stable. Would that burn anyone's biscuits?
