I've been using compat-wireless-patched-daily from AUR for quite some time and also compiled compat-wireless myself.
Since 2.6.37 I can compile and install compat-wireless but iwlagn modules doesn't get loaded properly. Don't know if this is related but it looks like modules are now compressed.
I used kernel 2.6.37-5 and compat-wireless-2011-01-30.tar.bz2 / md5sum: 58f059f8bf5247df73e4ebe71d6aeeec.
Here is the section of my dmesg during boot.

-rw-r--r-- 1 root root 46911 29 janv. 20:02 iwlcore.ko.gzI experience a lot of instabilities with the built-in iwlagn. How can I compile compat-wireless so it works with 2.6.37?
I've contacted Intel developer and compat-wireless package maintainer but no success so far.
Thanks
