I don't think it's much to do with Windows. Having the 32 bit driver run on a 64 bit OS depends on how the driver was written/how it works. EG: A lot of printer drivers or USB device drivers(Wifi etc) just don't care.
Dual boot to XP Sp3 32bit is one way to maintain device compatibility for non supported devices. SO no need for anything to end, or change. Just ask commodorejohn. Kudos given.
@J-Golden. A response from Jens is obviously concrete, and first -hand.
