   Do you see this line? It says that the module you are trying to install is   
   invalid. It was probably compiled on a kernel other than the one you are   
   running,  or with a compiler other than the one used to compile your   
   kernel.

   You need to make sure that the old   
   /lib/modules/2.6.22-gentoo-r8/net/ath_ha1.ko   
   is removed, and that the newly compiled module is actually installed and   
   that depmod is run.   
      
      
   You also need to make sure that the kernel it is compiled for is actually   
   the one you are running.
