The patch is attached.  It not ready for applying and may need further
work, but should be OK as a starting point.  It can be applied to version
0.2.0 and the CVS version.

Use "iwconfig wlan0 reset 1" to force COR reset.  Use util/hostap_fw_load
to load the firmware.  The firmware can be downloaded from
http://www.red-bean.com/~proski/firmware/ (I don't have 1.8.2 firmware, so
please adjust the script accordingly to use 1.8.0 firmware).

It would be interesting to see the output of "cardctl ident" and "cardctl
config".  I'm not sure if the wireless part is function 0, which the
driver assumes in several places.
