This is supported by the iwn(4) driver in CURRENT, and it should be
quite easy to port the driver to 7-STABLE.  If you're interested in
reinstalling FreeBSD and testing a backported driver, I'm sure this can be sorted.
I am interested in doing this. Please advise on how I can get these bits.
I've got hold of a laptop with the 4965 chipset in it, if nobody beats
me to it I'll have a go at backporting the driver.
OK, I've backported the iwn(4) driver for the Intel 4965 wireless
chipset to 7-STABLE.

You need both of:

Loading if_iwn.ko make a nice reboot on my laptop.
No messages just a reset... FreeBSD 7.0-STABLE #29: Tue Jul 29 16:13:47 EEST 2008 i386
May be I should try with more recent -stable ?
http://people.freebsd.org/~gavin/iwn-7/iwn-7.diff

Both are relative to /usr and are against 7-STABLE (although may well
apply to 7.0-RELEASE cleanly).

Please note that there are a couple of issues with this driver that
aren't seen with the driver in -HEAD.  Firstly, it only supports B/G
channels, it doesn't work with 802.11a.  Apparently this is due to a
firmware issue which the driver in -HEAD works around, although I don't
know how yet.

Secondly, there may be a slight issue with regulatory domains.  I'm not
certain about this, but I was seeing issues while trying to associate to
an access point on channel 13g, changing the AP to channel 1g fixes
things.

Even with those two caveats, I can say that so far in my testing it's
been working very well.  However, even if the driver works for you, I'm
pretty sure it's too late for a merge before 7.1.

Lastly, as the laptop is on loan to me and I'm going to have to give it
back soon, I don't know if I'll have a chance to do any further work on
this driver.  I'm still interested in stories of success or otherwise.

Thanks,

Gavin
