mwifiex is not integrated in the last compat-wireless release from today
it will be in compat-wireless-2011-04-01.
The kernel version number in the compat-wireless release is the version
the code is from. So compat-wireless-2.6.39-rc1-3-s is based on the
source code from kernel version 2.6.39-rc1, it should compile and work
with every kernel from 2.6.24 to 2.6.39.

You could build your own version based on the latest version of
linux-next. It is described at:
http://wireless.kernel.org/en/users/Download/hacking

I created a self made version with the lasted fixes for compat-wireless
and and mwifiex at:
http://hauke-m.de/fileadmin/openwrt/compat-wireless-2011-03-31-1.tar.bz2

Tools using wext interface like iwconfig will not work. To activate it build your kernel e.g. with CONFIG_LIBIPW=m."

This just says that the wext interface will not work, because your
kernel was compiled with CONFIG_WIRELESS_EXT=n, if you do not need wext
just ignore it otherwise compile your kernel with CONFIG_WIRELESS_EXT
enabled.

This is a bug which will be fixed in the next release. ;-)
Build your own compat-wireless version from git, wait till tomorrow or
use my version at this will be fixed.
