I ended up add the unaligned-access patches to my 2.6.24 kernel to get 
the wireless-testing code to work.
That along with some minor updates to the iw_range struct in 
include/linux/wireless.h

Once those patches were added an incompatible pointer type came up when 
compiling.  The source was lbs_process_bss() in scan.c
code:     

 if (*bytesleft >= sizeof(beaconsize)) {
                /* Extract & convert beacon size from the command buffer */
//              beaconsize = get_unaligned_le16(*pbeaconinfo);
                beaconsize = le16_to_cpu(get_unaligned((__le16 
*)*pbeaconinfo));


Once I commented out the new get_unaligned_le16 and returned the code to 
the old line it went away. 

I was in a huge hurry when I did this so I didn't take the time to 
figure out what the problem was and fix it correctly.
