I am using a 2.4.26 kernel.  That may be the difference.  I have not heard 
of anyone able to get madwifi from October or later and wpa_supplicant 2.5 
working on an Atheros card with a 2.4.2?.  Same with ndiswrapper 0.11.  I 
took a look at ndiswrapper 0.12rc1 but it appears to not compile with a 
2.4.26 kernel.

So the people I know and myself who use Atheros cards are forced to use 
driverloader at this time or try upgrading to a 2.6.x kernel and see if that
