Howdy.  :)

(btw, I'm CC'ing the backports mailing list, which is a better place to=20
 ask these sorts of questions)

I found that the backports cross-compile process worked much the same=20
way as building compat-wireless.  This is what I'm doing currently in my=20
build script:  (This is using a backports package generated last night=20
using the backports git HEAD code with the cw1200 driver integrated)

 set -a
 CROSS_COMPILE=3D${CROSS_COMPILE}=20
 ARCH=3D${TARGET_CPU}
 KLIB_BUILD=3D${DEV_PATH}/${LINUX_DIR}
 KLIB=3D${TARGET_ROOT_ON_HOST}
 set +a
 make oldconfig  # menuconfig worked here too
 make
 make install

That said, the 'make install' target isn't currently sane for=20
cross-builds due to the bacport_firmware_install script not respecting=20
prefixes.  I just commented that script (and a few others like initrd=20
updates) out of the Makefiles, and I had a successful build/install.
