Which couple of fixes?

To rule out if its an ath9k issue you can try
compat-wireless-2.6.36-rc1 from here:

http://wireless.kernel.org/en/users/Download/stable/

and install it on an older kernel, you can use ./scripts/driver-select
to only enable ath9k to compile.

I've been using pm-suspend on this release for a few days now without
any issue but I am using an AR9003 chipset. What chipset are you
using? Can you provide the dmesg output upon module load?

That's a bug, a regression likely.

Yeah very likely.
