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.)
