I have some work in progress patches for that. They won't work yet (in
fact I just ported them to a newer version of compat-wireless without
testing, so they probably won't even compile yet *g*), but according to
my rough estimation, they contain about 70-80% of what's necessary to
support this hw. You can find them at http://nbd.name/ath5k-wisoc.tar.gz
If anybody is seriously interested in hacking on this stuff, please take
a look at this patch series and contact me afterwards...

What platforms with old kernels are you using? Maybe some of them are
being worked on in OpenWrt already ;)
