compat-wireless-old is deprecated. I forked off a new compat-wireless
since mac80211 added multiqueue support a while ago, but recently
compat-wireless started to get support for older kernels again because
mac80211 stopped using the multiqueue support. By default the stable
compat-wireless releases up to the ones based on 2.6.32.3 had support
for kernels >= 2.6.25. Then if you enable only ath5k or ath9k you can
go even lower, to 2.6.23.

This all changed again for 2.6.32.4 where mac80211 once again
re-enabled multiqueue support but I did make an attempt to actually
backport that this time [1] down to 2.6.23 and actually even lower
kernels. That release hasn't been tested yet though so I'm waiting to
hear about results. I may get a chance to test a 2.6.23 kernel with
that snapshot at some point today, we'll see.

So apart from compat-wireless though you actually need the full SoC
support though and that is provided by openwrt but I am not sure down
to what kernel that is backported to. In any case you are better off
just upgrading to a newer kernel as others recommend.
