At least in the source to the 2.6.24.2 kernel I downloaded from  
kernel.org, the hostap driver doesn't appear to support radiotap  
headers.  If that's the case, you will not be able to get radiotap  
headers from your adapter, as the software doesn't support it.   
("iwconfig wlan0 mode monitor" isn't guaranteed to turn on radiotap  
headers - especially if the driver for the adapter is incapable of  
generating radiotap headers; it just puts the adapter into monitor  
mode, which might have no radio header, or might have the Prism or AVS  
radio header rather than the radiotap header.)
