I just got a new HP dv5z laptop with a/b/g/n wifi adapter; it claims to be an
AR5009. Googling for the PCI ID (0x002a) matched it up with AR9280, which led
me to the ath9k driver. It's not currently provided with the compat-2.6 tree
but I pulled a copy from the wireless-testing branch and added it to my compat
tree.
It needed 3-4 definitions to be added to <linux/list.h> but otherwise compiled
OK and it's now working fine for me in 2.6.26.3. Did you already have plans to
include this driver, should I post my diffs?

This patch enables building the wireless-testing ath9k driver with the
compat-wireless tarball at
http://www.orbit-lab.org/kernel/compat-wireless-2.6/2008/08/compat-wireless-2008-08-06.tar.bz2
In addition to applying this patch, you must also copy the
drivers/net/wireless/ath9k directory from the wireless-testing image into the
compat-wireless tree. Just posting this for posterity since it seems that it
won't be needed for much longer.

Thanks. We can fork wireless-testing for old kernels based on this for
compat-wireless. Problem is updates. I suppose each driver maintainer
can supply updates when they want. For that please use compat-masters
list.
I'll create a new tree for this when I get a chance. The list.h changes
should have what we have in the kernel. Although list_splice2() is
functionally equivalent I rather use what the kernel is using the name
will be different though of course.
