From the maintainer, Elmer Joandi(sp?):
	aironet4500 is superseded by cisco340 drivers (airo.c) by Ben Reed
and the  only strenght of my driver is that it allows to access absolutely
all registers on card. Which is useful for developers only. Besides there
is no normal interface to configure crypto in my driver, as the general
interface is not userfriendly at all. So in fact, I use Bens driver for my
ISP bussiness in general cases and my driver for troubleshooting.
