Help! GPS USB problem

Just bought a new computer to support my flight sim habit. For the
first time since the SubLogic days, I'm flying without a stutter. I
digress.

I have a Garmin 196 with the Mapsource addon. I was able to reinstall
the Mapsource application on the new computer and successfully unlock
it. I cannot, however, get my USB card programmer to work.

After a preliminary investigation, it appears that computers that have
a Via chipset for the USB controller are not compatible with Garmin's
card programmer. Can this really be? Am I dead in the water on this
one? Do I have to keep my old computer set up just so I can program
my little proprietary Garmin card? I think I feel myself gravitating
toward Jay's point of view. Help!
