If you want to pursue this venue, this is a wrong place to ask.

Try working in two directions.  One is updating your kernel.  Maybe 
there is a newer kernel for your platform.  Or maybe you could apply 
patches that upgrade your kernel to 2.6.23 and even to 2.6.24.

Another approach is backporting compat-wireless to older kernels.  You 
only need to "bridge" two kernel versions to go from 2.6.24 to 2.6.22.
