Just one small note:

ath9k is in compat-wireless-old but its only enabled in
config.mk for kernel 2.6.26 as that was the only we tested
it on. Feel free to tweak config.mk to enable it for older
kernels like 2.6.22 and see if it compiles. If it doesn't
you may need to patch up ath9k in it. If you do so please
send the patches and I can apply them to the git tree.

2.6.21 is supported in compat-wireless-old but PCI was
never tested. It may work, someone just has to test it.

Mind you my advice is to just upgrade to at least 2.6.27.
compat-wireless-old just doesn't get a lot of love, but you
are more than welcomed to send patches to help port stuff
from wireless-testing to it.
