You can build your kernel package on your own. This Makefile can help you. You can download this Makefile, and put all driver source code to a directory called “src”. Create a directory can put your Makefile and src directory in it. And put this directory to your openwrt source(openwrt_sourcecode/package), run "make menuconfig". You can see it in Kernel module -> Wireless.

I have tried it but I failed to compile it.
