Not to nitpick, since maybe the Newegg link is somehow stale already, but their description of the DFE-530TX+ seems to say that it's a 10/100 card, not gigabit.
There's an OS/2 driver for at least *some* of the RealTek gigabit cards, which are super cheap on eBay, FWIW. People bust on RealTek but I've always had great luck with their stuff.
