Nokia N95 worked fine at us too, no problem experienced. As far as I
remember we have also an iPod Touch here (therefore I don't understand
why it haven't already been tested), I'm going to test it myself with ath9k.
The interesting thing is that by turning WPA/WPA2 encryption suite on
(but strictly with only CCMP since TKIP is not supported by 802.11n) our
other Samsung mobile (a Samsung Omnia), it has been able to work
perfectly, without any problem. I would have thought that i780 and Omnia
has somewhat similar wifi subsystem/chip/anything, but now the situation
doesn't seem to be that. Perhaps i780 is more similar to Adam Cécile's

That can be a problem and thank you very much for the idea.
Unfortunately at this time I'm too overloaded to make a try with
2.6.29-rc5, since it would involve several changes in our environment
(build system, patches, tuning all the components etc.), and now I'm
under a rather high pressure to get our product into an as final state
as possible to the Cebit exhibition. Luckily, I have an other colleague
who could be asked to perform such tests, or at least prepare the
environment to me thus saving a bunch of time.
I'm going to report the results of these tests - it can take up 2-3 weeks...
