To quote Netgear:
"At launch, the GA302T will work with all popular Windows operating systems, including Windows XP, Windows 2000, Windows Me, Windows 98, and Windows NT. Moving forward, we expect to offer drivers that will work with other operating systems."
I would like to think that a Netware driver would be one of the first they would develop, but I have seen no trace of one to date.
Considering how new (and the performance level) of the card, I doubt you could use a generic driver or another card's driver. I know this isn't what you were looking for, but I hope it helps. I personally can't stand seeing Novell/Netware treated like a second class citizen (despite its speed and reliability advantages)...but that is the enviroment we live in. It's not the first time a superior technology lost out because of stealth marketing and FUD/hype (Alpha processor, anyone?)
