2.6.33-rc2 config

After upgrading to 2.6.33-rc1 (and now -rc2) I can no longer  use my iwl3945 card.
There's nothing suspicious in dmesg. (But output attached for all cases).
iwconfig returns: wlan0     no wireless extensions.
iwlist: wlan0     Interface doesn't support scanning.
lspci output:
04:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
Please contact me, if you need any additional info.
Thanks for assistance and merry Christmas!

Dmesg output
Comment 2 John W. Linville 2009-12-28 17:13:34 UTC
Did you do "ifconfig wlan0 up" first?
Comment 3 Radek Pilar 2009-12-28 18:06:04 UTC
Yes, of course.
Comment 4 Reinette Chatre 2010-01-05 00:11:34 UTC
could you please load module like "modprobe iwl3945 debug=0x43fff" and then send dmesg output from that as well as after you have run "ifconfig wlan0 up"

Comment 6 Reinette Chatre 2010-01-05 17:22:04 UTC
Could you please set CONFIG_CFG80211_WEXT in your kernel config file?
Comment 7 Radek Pilar 2010-01-05 18:45:26 UTC
Weeell.. Sorry folks. I've apparently missed an API change... For the next time, I'll read the changelogs more carefully. With CFG80211_WEXT everything works fine (and I've found that "iw" works with CFG80211_WEXT disabled). So that's definitely my mistake.
