I have a new Netgear WG311 wireless card, too.... I have tried to install the madwifi driver from the cvs repository today on suse 9.0 x86_64 and this does not work. There is apparently some problem with the ath_hal binary that madwifi needs to run. The madwifi project doesn't seem to have any solution for this, so I am wondering if there is maybe some other way to get this card running...
would be interested to hear from anyone who has actually gotten this card on an amd64 to work.
thanks
