Yes, if he agrees on that. I am hoping that iwl3945 will be usable when
2.6.22 is released, but I won't add replaces=('ipw3945') for it,
maintaining the two in parallel for a while.

One user complained that it wasn't updated to 2.6.21, so I did the
update and he said it works.
We should definitely try the mac80211 or softmac one, as it has wpa support.

Yeah, it should be merged in the wireless-2.6 tree soon.

"CVS isn't under active maintainership,
but it now contains the rt2x00 version directly taken from GIT
(with some lag, since the updates are done on a irregular basis) and it
contains no backward compatibility code for older kernels."

That means we can use CVS with 2.6.22 again, unless wireless-2.6 has
some serious changes compared to 2.6.22.

There are still major problems with the driver. See IvD's TODO list in
the rt2x00 wiki.

mac80211 should be quite up to date in 2.6.22. Backporting drivers would
be quite a task, and I am not sure if I can do it, but it seems worth
looking at.
