Netgears website doesn't clarify what OS's are supported with their drivers. But I suspect they only added support for Vista x64 (and XP x64) to their newer drivers v4.x and 5.x.
Have you tried it or have you contacted tech support to ask? If not, I suggest you do.

Apparently the drivers dont support win xp x64 but do support vista x64. now the chipset is marvell topdog and I have tried the marvelll top dog x64 drivers but i cant get it to detect. I have heard of people hacking the .inf files and getting it to work for other models.
