Scratch all that, I can't even modify that directory's contents!
BTW, here's my 802 stack:
# lsmod | grep -i iwl
iwl4965 155012 0
iwlcore 122308 1 iwl4965
mac80211 181480 2 iwl4965,iwlcore
cfg80211 24968 3 iwl4965,iwlcore,mac80211
rfkill 11288 2 iwlcore
I do have the "rfkill" part of the iwl stack, but it only seems to "take
the state" at module load time. I.e., I can get the rfkill switch to
"reset" if I completely reload the stack as follows ...
# rmmod iwl4965 iwlcore mac80211 cfg80211 rfkill ; modprobe iwl4965
Not exactly my "plug'n play" operation.
Although the good news is that it behaves "just as good/bad" as the
Vista driver, works for open APs, doesn't seem to connect to my WPA one.
I'm currently playing with several options on the iwl4965 driver. This
is the stock Fedora 9 .14-108.fc9 kernel, as the newer "compat" builds
(for any kernel 2.6.24+) from iwlwifi didn't work at all.

I've disabled the 11n support, including for "50" (5000) series. I'm
thinking about using the "swcrypto50" option too, to see if it'll work
with my WPA2 AP.
Hmmm, nothing is working. Here are my current options that I'm playing
with (and adding/removing) ...
options iwl4965 swcrypto50=1 11n_disable50=1 fw_restart50=1 swcrypto=1 11n_disable=1 fw_restart4965=1
BTW, it won't seem to load the 5000 firmware anymore:
firmware: iwlwifi-4965-2.ucode
I even removed those 4965 firmware files. I'm rebooting to see if it
sees the 5000. No dice, it still keeps the old firmware. Sigh. I had
it loading the 5000 one time, but don't know how to get it to now.
