Help building compat-wireless

I'm struggling a bit to build compat-wireless in a cross-build environment. I normally don't build kernels in-tree, rather I use a build tree, e.g. % cd <linux-source>
% mkdir /tmp/kernel_build
% make O=/tmp/kernel_build <some_config>
% make O=/tmp/kernel_build uImage

I can't see how to use this setup with the compat-wireless package.
I tried [all the combinations I could think of] something like this:
% cd <compat-wireless>
% make KLIB=<linux-source> KLIB_BUILD=/tmp/kernel_build
However, this seems to not work as all I get are errors like this:
/local/compat-wireless-2012-02-28/config.mk:242: "WARNING: CONFIG_CFG80211_WEXT will be deactivated or not working because kernel was compiled with CONFIG_WIRELESS_EXT=n. Tools using wext interface like iwconfig will not work. To activate it build your kernel e.g. with CONFIG_LIBIPW=m."

Does this process work in my workflow? What do I need to do to get it going?

Does this process work in my workflow? What do I need to do to get it going?

I managed to get past this, using this
% make KLIB=/tmp/kernel_build KLIB_BUILD=/tmp/kernel_build but to get it to actually build anything, I had to append the 'modules' target, e.g.
% make KLIB=/tmp/kernel_build KLIB_BUILD=/tmp/kernel_build modules

Next problems:
* How do I select sub-options? I only want WL12xx support with SDIO, but that requires some sub-options to be set that don't appear to happen. I get the main wl12xx module, but not wl12xx_sdio or wl12xx_platform_data
* There are a number of files which don't build against my 2.6.37 kernel, but none of these are important to me (they are in the bluetooth driver which I don't need, but nonetheless it gets built)
* The make/install is terribly broken for cross-builds.

I hacked my way past these problems and finally got some modules which I can try. Sadly, they don't work at all:

# modprobe wl12xx_sdio
wl12xx: loaded
# ifconfig wlan0 up
wl1271_sdio mmc1:0001:2: sdio write failed (-110)
wl1271_sdio mmc1:0001:2: sdio write failed (-110)
...

Note: This driver in my kernel tree gets much farther than this - it will actually download firmware and talk to the device, so I'm pretty perplexed by this failure.

Any help greatly appreciated

Now, I'm getting this error:

Where can I find it?

Thanks.  Do you know if these will be moving to kernel.org anytime soon? My build recipes expect that to be the official home for firmware.

I believe Luciano submitted these a few weeks back, so all in good time :)
