I've used an Mercedes M-Class that has very similar technology (they're brand name is Distronic). It does the flashing light, and will auto-brake down to idle speeds.

In any case, for the near future if you want to run a 64 bit operating system you will either be using one of the free Linux versions or the free download of Windows XP-64 beta.

Or you'll be running Mac OS X...
