Fair point about a kmod not being an ideal place to start! I've tried to
read a fair bit about kmodtool and packaging kmods but clearly my
understanding is still rather limited. However I felt it was important
to start with a package that I actually use on a day-to-day basis so
that I'm in a good position to follow the development and
find/apply/create new patches.
I'd be delighted to have you as a co-maintainer - it would be great to
have someone to learn from and help answer any questions or problems I

I'll do that, and once I've taken a look through the spec file and done
some testing I'll submit it for review.

Hmmm... I have read very varied reports on this driver - some say it is
fast and others report poor performance - I am guessing that it could be
dependent on the specific chipset but I'm not sure. I'll try to collect
some info and see whether there are any patches in the wild that improve
performance. I am not in a position to really test the speeds since I
only use my wireless for broadband so the speed isn't really an issue.
For me the best thing about this driver is that it works flawlessly with
NetworkManager whereas the ndiswrapper/windows driver combo was badly
broken when used with WPA/WPA2 encryption and NetworkManager even though
it was fine when using wpa_supplicant scripts alone to connect (FWIW
I've got a 4328 chipset on x86_64).
